    I find through searching that upgrading to a 400 trans you need to adjust driveshaft lengths. Instead of getting my shafts adjusted, could I just find used ones for a 3/4 Suburban or 3/4 Longbox truck? I would assume they came stock with 400s.

    yep! alot of 81-up had the th400 in 3/4 tons especially with 14 bolt SF it seems, i see alot around here like that, they are the shorty 400 with bolted on output yoke, bolted to output shaft, they havhe a slip in them like a 4x4 rear shaft does because of the output style on tranny,

    what you needing to know ? anything else ?

    What I need to know is if I do find a used 400 possibly mated to a 205, if I can just purchase drive shafts for a 3/4 truck (burb or long box) and bolt everything on without having to get custom stuff made.

    well thats all gonna depend on total drivetrain length then,
    and also yoke style for front of case and well rear too.
