So it is just 4wd trucks that you would have to change the output shaft and the extension housing or would you need to do that with the 2wd truck transmission too?
.
No not just the 4x4s.
The motor home and big trucks and some vans used shorty tailhousings.
They have the strong guts, very good stuff.
Just use the long output shaft and housing and follow Tom Hands book.
