They are castor rims (normal 95s)
I just had to move it back from a space I had to do all the surgery for you guys. Since my garage is full with a school fundraising project right now, I think it will be 2-4 weeks before I can tear into it for you guys. Suppose I shouldn't have a hang up about working on cold driveway, but right now I do. Have posted phone number on PMs for all.
Bottom line, this is going to take longer than I hoped. Sorry about that, but we'll get there.
