Identify this style of drums and axle hubs

One might get a rule out. Might have standard bearings, but I'd wanna know the depth offset before i ordered parts. Those big holes ain't for mounting. My guess is cooling. This may not be a simple hub swap like others.

Idk, I could be completely wrong too.

You are correct, except drum would still share same surface, just on the backside verses front.

No way, do i think I'm right. But I'm intrigued.

 

Yeah, not sure. The hub looks short. I would assume the back of the hub extends through the center of the drum IDK

 

That’s an RA-351 10 hole bud.

 

The link i posted was supposed to be Webb. If you can find the drum on their online catalog you would know. Fleetprides online catalog may also have pics

 

Right off the top of your head I bet?

 

If I’m not mistaken they were made by Dana pretty much exclusively for international. They were standard equipment on the 4070’s.
