Think you need to change the input shaft to the gear driven case to mate it to an A343 (23 spline).
Can also use a housing from a Jeep AW4 (same box) to mate to other transfers.
Talk to Boof, he has done it with the Toyo box.

I will check with boof, i thought someone would have made an adaptor especally with how popular the lexus V8 conversion was. there must be people that wanted to maintain the gear drive transfer with the surf auto box.

Marks 4wd adaptors have the 21-23 splile couplers. I used one in my R150=gear driven tranfercase conversion

Buy the marks adaptor kit if you forever want to be chasing oil leaks... Ive got one on my R150 box behind the hilux, and it currently transfers all the oil out of the gearbox into the intermediate chamber and then straight into the transfer case. Tranfer cases SHOULDNT have 4L of oil in them!
Thats using all the supplied seals, which didnt fit the adaptor...
