Hey Doug, yes, they self adjust.

My Longhorn one ton has 13" rear brake drums and it looks to be in bad shape. Wheel was running loose and the seal went bad. The wheel bearings are rounded off, but the race is rounded as well. Lucky I didn't lose the wheel I guess. I will try to get mine turned. How difficult are used drums to find?

On my dads 3/4 70 we were able to reuse the rears but the front were shot so we got the replacement ones and drilled out holes for so we could adjust them. It might throw them off balance some but we couldn't feel it. We just drilled three or four holes where the originals were and then used a chisel and a file to make them ovals again.

The original wheel brgs are conical on these. The replacements are regular roller brgs.
We used to get the later model drums & drill out the hubs & use the larger studs.

I have an old Napa catalog. It lists drums for 13X2 1/2 in. sigle wheels part number 640-1363. I don't know if they are still available but you might call them.

Thanks for that part number. Is this a normal bearing then?

Here's the rear end:



Not a dana, right?

Definitely not a dana. This is the Dana 70 in our 69 D300.
