School me 9n a 1970 truck 8 3/4 rear

Rear 8s compleat has left hand studs on driver side
A castle nut on axel and the azeo 8s on the outside of the brake drum
It's not locked up. Has a sure grip center section he sa8d ht thought it had a 3.73 gear
Was in a 1970 dodge truck (can tell by the pads) that had a flat bed on it

Tapered axles on a '70?

Well it seams. The rear was changed at some point and not orignal to the 70 truck
The rear is out of a truck thou
Is the drum splined onto the axel?
At some point. Can I pull the axel. Install green bearing
Install new normal type axels along with normal brakes

Thank you very much[

Not without some modifications; they changed the bolt pattern at the end of the housing in '65...you can install the later brakes with custom axles and Green bearings but you'll have to re-drill the bolt pattern.
