ok guys, i'm getting a 74" dually 70 equipped w/ new 4.88's and a powerlock and the smaller drums. it supposedly came out of a f350. my question is:

since supposedly 99% of most 70 shafts are not resplinable and i don't have the $$ to get new ones, can i buy a local junk yard big brake 70 (i can get those a dime a dozen) and throw the new gears and locker and BRAKES onto it? the big brake 70's seem to be much shorter. will the backing plates and hubs all bolt right on?

thanks a lot- russel

also, does anybody know if the F350 dana 70 shafts are resplinable. probably not, but no harm in asking.
