65 FJ40 - Doing it the Easy Way (5 Viewers)

[TreadingLight]

9 Months into the build for the 69 FJ40 project, I'm still in the "welding sheet metal" phase. It's also morphed into much more of a crawler than I first anticipated, just based on the parts I've managed to scrounge up. Someday it will be pretty rad.

So when I came across something much more complete, I thought 'hey, I could fix the brakes and just drive this one!'. But maybe it's not quite as easy as I first thought it'd be. This rig is largely original, in all the good and bad ways. But it's not all Toyota-original.

All about that patina

The bifold door is awesome, but the spare tire carrier is busted and the tires are all ancient.

Nice seats, shoddy terminals at the fuel sender.

Hmmm, I've never been a fan of V8 swaps.

Dealer-installed heat? And someone moved the shifter to the floor.

The seller told me the brakes were leaking and the engine was tired. I can't say much about the engine health yet, but the brakes are in dire need of attention.

So first up, brakes. In the short-term, I just want to drive it. In the future, I'd like to swap axles for front discs and 60-series drums. I figured I'd start by swapping in later drum brake backing plates with 10mm fittings and a dual-reservoir master. Hopefully my donors have good wheel cylinders. I'll have to make new lines but this should set me up for that future swap to newer axles. Seems easy enough and I have most of the parts on-hand.

But when I got to the rear left corner, the lug nuts wouldn't spin off. Instead, the wheel studs were just spinning in the axle flange. Rather than employ care and critical thinking, I decided to cut/break the studs off and swap in a donor axle shaft. Along the way I realized this one corner had reverse-threaded studs. Odd. But I'd already broken several off so I was committed to the axle swap.

And then I found this.

16 spline axle? What the hell?

This put me in a bit of a bind. I had donor 10-spline and a 30-spline axles to swap in, but that obviously wasn't going to work. I thought I could keep the project moving by just replacing the studs. But this weird 16-spline axle takes larger-diameter-than-toyota studs.

All I wanted to do is sort out the leaking brakes, but now I have an axle mystery and no wheel studs.

I measured the diameter at the knurl of a toyota stud, and the knurled hole in the axle flange, and found the mystery axle needed studs with a knurl ~1mm larger. I then turned to the Dorman wheel stud catalog and found that the studs for a '93 Mercury Cougar have the same m12x1.5 thread pitch as Toyota, and a knurl ~1mm larger. I ordered a set and hammered them in, so at least now I've undone the damage I did, while converting the studs to normal right-hand threads.

Mercury Cougar studs have the right thread pitch and diameter, but they are a bit long. Annoying but ok.

But all this raises the question, what the heck did I buy? A largely unmolested 1965 40, but with a 327 SBC, 3 on the floor, and a 16-spline axle? Could this have all been installed by the dealer when the 40 was new? If so, maybe that would change my plans. It's kind of a cool time capsule in that case.

I don’t know about the axle, but the 327 was a pretty common dealer swap that was often covered by warranty.

I'm pretty sure it is a Toyota housing. Someone put the 16-spline axle and matching spider gears in.

Yay for another earlier 40. Not many of us out there.

I see you have the Hupps or whatever heater. Can you please take a pic of the engine bay where that mounts? Trying to see if the holes would line up with what I have no so I wouldn’t have to drill holes.

Sure thing

Two hoses pass through the firewall between the grommets, mounting stud underneath.

The upper hose on the intake, the lower hose on the water pump (return line).

 

[TreadingLight]

Anybody here shopping for FJ40s in 1965 have any thoughts on the axle? Was that a dealer upgrade for the v8?

I'm inclined to move forward with my plan to eventually swap in a newer full float 30 spline rear axle with drum brakes/ebrake, but I'm curious if the current setup has historical/sentimental value.

In other words, if I chop it up and use it to make a drill press stand, will the land cruiser gods forsake me?

Thanks. Are you able to see where the mount studs come through the firewall?

 

[TreadingLight]

I see one stud directly under the heater hoses on the firewall. I edited the pics above to show that.

The heater is securely mounted and doesn't rotate so i am guessing there is another stud or bolt on the interior side of the firewall. Not sure why nothing else is visible from the engine bay.

Seems like a bunch popped up lately.

You could probably make that housing a Full float with fine spline if you wanted.

Only with a disc brake conversion and cough, cough, GM brakes. Or the 4runner drotors. Or heavy custom fab. Plus new spider gears.

I'm going to try and track down a 70 FF rear, skip all the fab and adapters, and end up with a heavy duty Toyota drum with ebrake.

Ideally.

I also scored everything I need for a front disc axle with birfs, I just need a housing. And time.
