64 b body

anybody tub one ? how short is the rear end ? have a shorten dana out from my arrow truck 30 inches is this going to be too short ?

Mine is a round tube back half with16x33 tires on 15x15s and the wheels have very small back spacing. The rearend is 34" flange to flange. It may be a little short but you can run 16x16 and get away with it.
