I want to swap a 205 into a 241 application, has anyone done this? The truck is a 90 Suburban with a SM465 and a 241 case. I also have a 80' 400/205 parts combo. I want to keep the 4spd but swap in the 205. It's my understanding that the 4spd has a 32 spline tailshaft and I know the 205 case has a short female 32 spine input shaft. It appears that the bolt pattern on the 4spd is the older figure "8" pattern. I'm wondering if I had a old style 4spd adapter could I bolt the 205 directly up to the 4spd or will there be modifications? Has anyone done anything like this?
