if i don't get those axles from you, what axles can be shortened to those lengths?

Doc's info is correct, a pocket calculator needs a brain to work correctly....sorry for the wrong info.

Because of a step down in diameter near the splined end of the axle shaft, 28" is the accepted maximum length for shortening/resplining most axles and a 31" axle with minimum step down is needed but a rare few don't have a long step down and might finish out to 28.4"

its cool thanks for the photo which ones can be cut down.

all i have to is take the bearings out put in the 65 and newer bearings in it.

IIRC the bearings/axles between the 62/64 rear axle and the bearings/axles from a 65 and newer rear axle are not interchangeable.

1965 and newer wheel bearings will not fit your original axles. In addition, you can not reuse your original brakes or inner seals if you convert to 1-piece axles.

if i get that rearend i will probably end up gettin the axles from you then dr.diff
