Title: putting a turbo 350 in saread of a 4 speed
Post by: sandmechnaicyahoocom on October 28, 2002, 08:16:00 AM: I am looking at removing the granny 4 speed from my 74 k20 and putting in a turbo 350, i already have one with the 4 wheel drive shaft and adapter, but I read that the 205 t-case has different splines depending on the application, I was wondering if any one has tried this yet and how it worked, any help or suggestions would be greatly appreciated thanks RJ

If you can get one from behind another TH350 it will of course hook up, but also be on the lookout for a t-case from a 700R4 because they had the same output shaft as the TH350.
