I'm not having any luck around here locating a 57 or 58 caddy 2 door we can cut a patch out of. the man before me made one out of tin and bondo but needless to say it did not hold up vary well in the climate the car was kept in. need about half the wheel well forward and from the rocker to the bulge on both sides and only the skin. we don't need any inner structurer as it's not the same as caddy. no one I know of is making any patch panels for these cars. so there is nothing commercial around. we could try one off a different brand Hearse as we are mainly interested in the lip off the wheel well and having that shape right. encountered a few gentlemen that think they are mining gold on these cars. but there has to be some still left hit in the rear or that lost the rear to a couch
