Planning to get Crawl Box for TLC70 with 150F/151F tranny

[FX2]

Hi! I made some purchases from Marlin in the past. 
I've got a customer, who needs low gearing for his LandCruiser 70, he tells me that he has G52 or 150F/151F transmission matted with split transfer case.  He's going to count splines on Monday.  I'd like to find out if Crawl Box (2.28:1) will bolt to G52 or 150F/151F transmission and will work with split x-case? 
I am also going to get several pairs of HySteer arms from Marlin - just sold my cast ones 
Thanks. Andrey.

I could be completely incorrect here, but I thought only the RJ70 came with R151...And LJ70 with G52.
RJ70 has 22R motor, LJ70 has 2LT diesel.

If its the original gear box, has he checked the VIN plate?...Under "Trans/axle" it should say which trans it is...

You pose an interesting question...I am throwing around the idea of a Toyota motor swap into my FJ40, using an R151...If the LC splitcase could be used with one, i could still have the offset output, and not have to worry aboot centering it.

I've spoken with the guy  -  he uses 2LT with stock tranny and x-case from LJ70 in some project vehicle.  He has R151 transmission and it's 23 splines - that's for sure.  Now I'd like to find out if CrawlBox or ToyBox will work in this application.  He's running UAZ portals (Russian made axles), and the rear axle has dif in the center.
I am trying to call Marlin but they are experiencing high level of phonecalls.

Ok, it's drivetrain out of LJ70 with 2LT.  I got some pics taken - please see below:

I really cant help you anymore with this, but thanx for posting the pics.
I have been thinking about swapping an R151 into my FJ40. Was wondering what I would do as far as tcase output and the offset rear axle.
This might solve my problem. I might be able to swap my 74 4 spd tcase for one of those later split-cases to mate up to the r151, and use my current 23 spline tcase as a doubler.
