Need help with drum brakes on my 8-3/4

don't mean to steal a thread but its kind of relevant to me too.

I was detailing the duster and notice my rear drum has a hole (1/4 inch?) in the face (no anywhere near the pads) Almost like something drilled it?

So I think I'll change the drums in the back...

Question?
When I change the drums and the pads look good (just replaced last year, hopefully still good!) can I just adjust the adjuster screw assembly and be done?

Nice photo abodyjoe!

Aloha!
