No locking hub at dana , just locking ring
To be fair, DANA-SPICER proper absolutely still offers upgraded heavy-duty axles with locking hubs.

CDan mentioned to these same prototype units. I've never seen one and only heard the same anecdotal stories about them. As they were prototypes and not production units, there would be no EPC evidence of them. Have any photos by chance? I did a quick search here on Mud and couldn't find anything more than discussion. @orangefj45, have you ever seen a factory full-time 4WD 4x Series t-case?
I guess if we delve into the prototype variants that did or could exist the history of Cruisers is very different. I've seen some random stuff around the globe that was purportedly a Toyota prototype, some obviously are not, others could be? Toyota doesn't offer a ton of info about their prototypes to this day.
Have some other pictures on a hard drive back from 2007 when I bought it.View attachment 3510198View attachment 3510199View attachment 3510200View attachment 3510201View attachment 3510202
Do you have any pictures of the actual full-time t-case and linkage setup on that side of the t-case? What does that cable do? What case is it? I'm curious how you know it was a Toyota built prototype and not something a company or individual did in the 30+ years prior to your ownership? What was the mechanism to balance/lock/slip between the front and rear outputs of the t-case? Clutch? Differential? Viscous?
All I see is a factory shift knob that says H-N-L but that could be slipped on any shift lever as it was available as a new factory part for many years on 4x/5x models.

A Cruiser with the 'Magnet' style FD engagement could easily be setup to engage the FD when it's shifted into L4 as those cases had a switch on the top that recognized when they were in high or low, unique on that era case, they are still very much part-time cases however. They just use a switched solenoid to engage FD versus direct linkage or a cable opening a vacuum valve and engaging the FD via vacuum diaphram.

A number of threads about these full time 4WD prototype cruisers. JohnnyC when he was around did some research. He found out Borg Warner had a facility in Japan at the time and working with Toyota.
l I have pictures of the underside. The torque tube behind the transfer case is custom. Uses the stock hole on the left side. Right side one is further back. The original hole for the torque tube is there unused. The transfer case has a adapter to use the standard hand brake.
I knew about this one for over ten years before I bought.
Not sure where you buy a floor mat without transfer case opening cut out. same with the transmission cover. The two for the transfer case the nuts are welded to the underside like the transmission. Cruiser has 4,500 miles. I've never driven it in all the years I've owned it. Floor mat doesn't look like it has over 100K miles.
VIN plaque lists the transmission as a M42.

This floor mat is made for four speed with bucket seats. It's the same as other four speeds up to 1\79. Prior to 9/72 the tunnel cover is shorter and would be short side to side on 9/73 to 1/79. Not sure what was used in markets like Australia in 73 that had a different four speed during the 73 model. Some would have gone to a lot of work to make that unused torque hole like it have never been welded. Johnny and I had a bunch of emails about the full time 4WD. He never had anyone denied it just no one he contacted remembered back to the mid seventies. Toyota is not known for sharing to begin with. I know @lcwizard seen it back when the previous owner bought it and was convinced it was a prototype.
During the first "gas shortage" in the late 70s, Toyota got together with Borg Warner and built a Full time T-case for the 40 based on the JeepAh, good intel on the trans/tunnel seat configuration. I'm pretty sure that the 1975+ GEN 40's with the factory 3spd had the traditional 4spd trans length tunnel. However I can't say I've ever seen one with a magnet type t-case (FD and H-L lever on dash), 3F (or column) shifter AND bucket seats so it's a long shot that the prototype floor mat came from one of those. Amazing stuff, I'm still looking for something less storied but it's fun to dig into regardless. Either way, it ain't factory built.
Edit: threads on the full-time 4WD prototype FJ40 subject for any that want to dig into it:
Have you ever seen a 76 FJ40 with full time 4WD?
Have any of you guys seen a 76 FJ40 with a center diff and full time 4WD?forum.ih8mud.comFJ40 for sale
I have a very rare FJ40 for sale. I have always intended to restore it but with 5 kids since I bought it I am just not going to ever get to it. It is a 1976 with full time 4 wheel drive. I was a factory prototype that used the same transfer case as the Jeep Quadra-rac. It has the appropriate...forum.ih8mud.com1970 model claimed to have "factory constant 4WD"?
This cruiser has been on Aussi eBay for some time now: And this is what the seller claims: Has anyone got an opinion on whether "factory constant 4WD" was really available as an option back then? Surely such a "special delivery" would cost more (because it always costs more to...forum.ih8mud.com

Quadratrac T-case. It had shifters on both side of the tranny shifter. They never got into full production and DOT approval so they were sold off to public entities like schools. A customer acquired one back in the 90s that was used at a high school to push football sleds around the football field.
It only had a few thousand miles on it. I thought it was custom at first but everything was Toyota, down to the glovebox shift pattern plate .
That floor mat looks about right
Ah, good intel on the trans/tunnel seat configuration. I'm pretty sure that the 1975+ GEN 40's with the factory 3spd had the traditional 4spd trans length tunnel. However I can't say I've ever seen one with a magnet type t-case (FD and H-L lever on dash), 3F (or column) shifter AND bucket seats so it's a long shot that the prototype floor mat came from one of those. Amazing stuff, I'm still looking for something less storied but it's fun to dig into regardless. Either way, it ain't factory built.
The mat is 1/75-1/79. Opening matches the four speed. Can see the rib in the mat around the transmission opening. 9/73+ the three speed and four speed shared the same boot for the shifter. Transmissions didn't. 9/73 the boot changed for the three speed. It was larger than previous years
But the three speed and four speed shift towers were in different locations on the floor. This one is for a four speed. The size and shape of the transmission covers changed 9/72 and didn't change until 1/79. 9/72 transfer boot changed. 9/73 both boots changed on the three speed. Transfer was the same as the four speed transfer. Three speed transmission boot is rare here because it was only used 9/73-1/74. Quick search a dash mounted high low ended 2/75. What makes this mat 1/75+ is the opening for cowl drains. 74 the drain from the cowl ran threw the firewall.
To me the frame says Toyota built unless you could order a frame with a special mod. Can't see any other way that torque tube could be installed other than at assembly. Someone was committed to not just modify a stock frame. Watching the video on the first GX550 off the line could see making a prototype coming off the product line. Back in 1975 was that possible or was it on and off the line. Everything but the frame something else other than factory is possible. The only two know are both early 76s made in late 1975. Newer has the cable to lock the transfer case moved to the dash which would be more a convenient location. Have a few pictures for the other one in an old email. One shows that knob. This isn't my cruiser and not going to post pictures of someone else's cruiser. I know JTO mentioned it on their website at one time. Maybe someone has seen it in person.
I worked on the truck and ran the ID plate. It was definitely a Toyota built combination. The t-case was factory mated to the Quadratrac. I can't recall the part number. I believe the Jeep version was a 1339 and the Toyota version was one number off. Maybe a 1340. I never looked into why Toyota dropped the project. Probably because the Quadratrac T-case wasn't all that great of a case. The project was probably started before the gas shortage. I knew of two, both were 1976 models I believe. maybe 75 but pretty sure they were 76's. Absolutely sure that they were factory built. Too many "Toyota" details in the build to be somebodie's crazy project.
Whatever the reason, only a handful ended up in the USA . The one that I worked on had been donated by Fann Toyota to the Deer Valley school district
who sold it to a customer of mine
Great intel on the mat. I've never seen a 1/75+ 3spd mat in person, vehicles only.
Sorry, I was under the impression you owned it. Is the current owner here on Mud? Willing to share his/her name?
You were able to run the ID plate and get the EPC or some Toyota document to show the Quadratrac transmission? How and where? This is information levels I've never seen on an early Cruiser and certainly would be a massive benefit to the Land Cruiser Heritage Museum and Cruiser community if there were a way.
At a minimum we may have different definitions of factory production built. Arakawa Auto Body definitely did custom projects on behalf of Toyota and/or end users, an example would be this Kyushu Electric Power patrol car.

Another would be this 4-dr BJ74 built by Arakawa Auto Body for Nagoya Diesel

I personally don't consider those production builds rather custom spec builds.
