Denny, I hope I wasn't stepping on any toes by my suggestion. I found an old link where you shared some pictures. I couldn't get them to come back up, that's why I threw your name out there.
On cutting out the rim centers, I've been contemplating this for a while. The centers on my 54 are riveted on. I'm hoping with a grinding wheel and an air hammer, I can get them off without too much damage. I found some rim blanks that should work. I'm planning on making a jig that sits over the top of the rim and I can adjust it at 4 different points and tack the centers in place. Then I'll put them on the spin balancer at my Dad's shop to check to see how true they are. After that It's the final weld in.
