It's all good! Love you guys. Don't go nuts with the mallet! Just use it to get them started. If they are on the car that's about the only way I know of.
Hit with a rubber mallet from the outer edge and hold down other side with your hand as you pound. When I say outer edge I mean the edge closest to the tire. So your are pounding in sort of toward the rim and down at the same time.
I have a set small bolt ralleys with 70-71 caps. Blasted and painted 250.00. I have rings but they are not perfect. 280.00 with rings. I'm in Uniontown Ohio and will be at the Canfield swap meet Fri. and Sat.
