If I had read four more pages if this build thread I would have come to page 48 where he describes with great photos and a video how his mechanic removed 1" from the input shaft. I did the same thing to mine today. A spacer would have put the shifter too far back and the old R150F with the short input shaft has a 5 bolt tail housing wheras the '96 and newer R150F has a 7 bolt tail housing. There is no good way to put the driver side output tansfer case for 7 bolt housing on the pre '96 R150F with 5 bolt tail housing. I came to the conclusion that the only option for this swap is to remove 1" from the input shaft.Thanks for the info! There is so much confusing info regarding this conversion. I read so much saying it was the other way around. Now I have read this build:
On page 44 it looks like he is using a 5vz R150F. I guess it's back to the junk yards to find the right trans!

The finished product. The splines are hardened so grinding them off is necessary. I spun it on the lathe and used a small grinder to remove most of the material. I finished it with a carbide tipped lathe bit then used a file while spinning it to smooth and straighten the pilot bearing surface. It worked very well.
