5 lug rear axles

[ron19]

I'm junking a 76 Chevy big 10 that I took the front disc's off for my 65 (Note: I think the spindles are larger than a standard 1/2 ton but not sure)

My questions is, does anyone know if the rear 5 lug axles out of the 76 big ten 12 bolt rear would swap into the 12 bolt rear in my 65? That would save buying the axles out of CCP or somewhere else.

The rears measure close to the same, but not sure if they would actually install, has anyone tried this? I've got the scrap man coming tomorrow afternoon to get the truck, but I'll have him wait if they will work.

Thanks guys!
