Anybody done a 400t-4500 swap on a 4x4?

I've never seen one of the round bolt pattern 205's in person. I've read that they were out there just rare.
Did it bolt up directly to the 4500 or was a custom adapter needed?

There was about a 3/4 or 1 inch adaptor or spacer between the trans and transfercase. The previous owner said it was advance adaptors part.

this is correct if you dont swap the input, the newer round pattern 205s have an input that is about 1.625" longer that the older figure 8 32 spline 205s. the inputs are a direct swap for one another and if you go that route no adapter is needed. when i did my swap in the jeep i used the AA adapter plate because it was cheaper than buying a new input. not to mention without it the driveline was that much shorter to the front and i wanted to avoid that.

the round pattern 205s started in mid 85 and continued until they quite production of the squares v30s.

here are a few pics

this was out of an 86 k30 i also swapped in a 32sp front output from a dodge



guts everywhere



this is the AA spacer ring







i cant remember from the build if the 1350 CV would have gotten into the tailhousing on the tranny if i had not used the spacer as well. it may have been an issue.
