Thanks for the reply, I lost my password for a bit, finally re-set it. I got it figured out. Just wanted to wrap it up in case anybody else needs to know.

The wheels were standard enough and I got the correct lugs.

1. to confirm the seats, I pressed some clay into it and compared it to a known good lug. I put some plastic wrap around the clay ball first to keep it from sticking.

2. to clean and de-burr the seats, I bought an open-ended lug nut, a bolt that matched, and a regular nut to lock the lug in place at the end. I grinded two slots in the lug face and carefully spun it in the seats using a cordless drill and some lube. turns out it was mostly discoloration, but I'm 100% sure they are clean and smooth now.

3. to check the depth, make sure they weren't bottoming out, I took them off and colored the bottom with red marker, then put them back in fully tight, then took them out again and confirmed that the marker was not disturbed.
