tranny swap driveshaft solutions?

I am considering swapping my old factory MS465 4-speed with a turbo 400 . I have the turbo 400 in a 69 3/4 ton right now and am wondering if the driveshaft from this truck will be of use if I change my 72 1/2 ton to the automatic. Will the driveshaft from the 69 be the right lenght? In other words can I just swap trannies and front driveshafts ?

You should be able to just swap the front half of the driveshaft providing that the trucks have the same wheelbase but with these trucks there always seems to be a lot of differences in driveshafts.

Re: tranny swap driveshaft solutions?

never swap half a driveshaft without having it reballanced as an assembly!


if it does work may as well get a new carrier bearing and some good u-joints while youre there.
