little update
Advance Adapters supposedly exclusively sells the marks 3.1 tcase gears here in the USA.
LC 80 100 Extra Low
although advance is totally clueless about the gears they eventually figured it out after i personally spoke with marks about Advances cluelessness. Marks emailed advance with the info and advance finally sold me the gears today. I told the Marks international rep they need to let Christo sell the 80 series stuff if they ever want to sell it stateside. Marks told me they need to let Advance have all their product line. Something about how andvance sells the yota stuff to americans and Marks sells all the advance stuff to the aussies. Thats fine but AA knows nothing about the 80. Christo should be selling the 80 stuff.
anyway i just got off the phone with AA and baught the 3.1 gear set for $931 shipped to my door. I paid $105 for shipping. before tax the cost was $777. if you are willing to wait for the AAshipments you wont have to pay the shipping fee but i dont want to wait.
also baught a used tcase from RI and it will be here next week. will keep updated
this will be my new low range: 2.98x3.115x5.86=54.4
....until i can go lower. pending

been pushing the yota vendors to make a lower tcase gearset for the 80 series. check it out at https://forum.ih8mud.com/hardcore-corner/252366-atlas-adapter-fj80-rumor.html. i am interested trying to get more people interested!
It's been a week! UPDATES! Just kiddin'
SMF.
SMF.
Let us know how you like the gears and if you ever miss the regular low range....you know how us 80 series guys are.

waiting for gears, tcase, and winch. i want to order the needed seals and bearings for the gear instal but i dont know what to order until the gears get here. i hope they have instructions as to what to order. sigh sigh. if i wheeled a tenth of the time i spent on this forum....im going to watch ultimate adventure again...

the marks gears arrived as well as a used tcase i got from RI with supposedly 66k miles on it.
started by removing the output and splitting the case. the marks instructions are easy to follow and refer repeatedly to the service man-referencing specific pages and pictures.
this is as far as i got. the gears on the tcase dont look warn at all. probably never been out of high range.

Dusty,
While you have that extra tcase, could you take a a couple of measurents and specific pictures to confim my beliefs?
1) I believe that the tcase-transmission bolt pattern on an 80 series A44*F is the same as 60 series A440F.
2) I believe that the 62 A440F output is the same bolt pattern as the 4sp 60 series. (This should be confirmed already since people have converted to the manual tranny before without any adapter plates.)
3) The spline count and diameter of the 80 series A440F transmission is the same as the 60 series 4sp output.
4) The 3 statement above being true, one should be able to install Marlin's toybox with minor modifications. The best part is the 80 output is just a stub, and is already cut off similar to what has to be done to the 5sp H55 Toybox. I do not think the Toybox need the tcase to capture its output shaft.
My understanding of the toybox is that the tranny output does not go thru the toybox, and the 80 tcase just needs a stub to feed the power and not need the thru shaft to support the gear set like a 60 series tcase.
I guess we need a pic of the back of the transmission, the front of tghe tcase, with a couple of dimensions between bolts and across the pattern. We also need the amount of projection of the output shaft from the trasmission. This should tell us how much of the toybox input will reach the output shaft and how much need to be cut off the output shaft of the Toybox.
If the bolt patterns are the same then the adapter plates from the 60 series should work. Only issue being spline engagement.
Edit: Oh crap, I just realized you have the newer transmission right??? The A3**?

i will try and take a pic and put up some measurements
This is what happens when you have one monkey banging on metal. Should have given me a call so there would be two monkeys banging on metal to equal one slightly evolved homo erectus 
.
Decided to try and tackle the pinion I see. You do have another choice... pull the origional and take the pin out of that one.
Give me a yell and I'll help you set things up.
(by the way, did you see my shackles I left there? we were so into the t-case when I left I forgot to grab them).

Hey Dusty,
Finally had a chance to stop in and take a look at your build page. That is a pretty mean looking machine you got going on. When do you think you will have that bad boy ready to climb some hills? Better yet, when ya goanna drive it to work, post that on the site.

That is always a great site when you tire is practically at the roof line of the guy parked next to you at work, lol. I look forward to seeing that pic.

sorry no pics. parts comming in. pile starting to reform on the floor of the garage:
HID lights
tmax comp winch with synthetic line-with quick disconnects (move it to back of truck PRN)
puma compressor
slee CV front shaft
full size 42 irok spare-where to put it?
cdan sent my tcase parts. here anytime.

Dusty,
Forget the measurements. I figured it out.
Thanks,

1) I believe that the tcase-transmission bolt pattern on an 80 series A44*F is the same as 60 series A440F.
3) The spline count and diameter of the 80 series A440F transmission is the same as the 60 series 4sp output.
so what is the verdict?
The pattern is not the same. The two transmissions have different rear case adapters, but it looks like one might be able to remove the the rear adapter and output shaft from a 62 series and put it on the 80 series tranny. It looks like it can be done without opening up the whole transmission. This is from the info I deduced from the EPC. My understanding is that the splines are the same, just the shafts are shorter as the 80 series t-case does not have the thru shaft. I have email to Rodney, to see if it can be done.
If so this would open up the options for the toybox and converting to a part time case as well. I guess one jus t needs to relocate the fuel tank to the rear behind the axle to make the toybox work.
