Maybe this is helpful. Here's a pic of some input shafts from Marlin's shop. The AR5 input shaft is on the far right. The 96 and Later R150F input shaft is in the center. Marlin made the AR5 input shaft fit into Mike Woods R150 but I'm not sure what version of the Toyota tranny he used.

Looks like it's got just enough UMPH to make it work.

This info from Marlin's board:

"Isusu chose to use a rearward pull clutch so I had to modify a Isusu front nose cone and the Toyota input to accept the larger 1 and 1/8" Toyota input shaft. I had to use the 96' and newer R150F trans with the longer input gear and extend the pilot tip as well. My extension slid into the factory Isusu pilot bearing.
Because the newer input gear does not mesh with the older (86-95') countrshaft, (greater helix angle), I was unable to use the 4.31:1 R151F trans
Yes, I used a 10.5" Toyota disk made by centerforce for the chevy V6, V8 converson.

I am doing this from memory, it has been a couple of years since I did the two conversions.

Marlin"

Oh the joys of fitting together non-stock parts!
