I said I would get back with you this a.m. I asked my brother about removing the skins he said you can't get the skins off. He said to look in the very old tool box for curved and edged hammer dowel's. Have not looked in Dads tool box in years, still a little concerned he will come back and chew me out. Low and behold it was full of old body dowels I think he used them on his 48' Buick. Anyway enough of that I tried one that is shaped like an airplane wing, used a copper hammer and tapped for an hour and a half. It works! The zinc back was no problem, found a guy in Orlando (used him many times), that will put some type of electro plate on them for $48;00 each. Mine are for a 42 Chevy car. But give it a try, there are plenty of auto body shops in this old town but the old timers are gone, you may be able to ask and find some for scrap price. Or you can send them to me only cost would be shipping, I love to do this kind of stuff, I'm getting closer to 80 and it will keep my mind off women. Doc
