Concours Parts have them. $94.95 each. I believe they are probably made by EMS and if that is the case they are HAMB members. Regards
I have a lower left front fender patch panel that I used a portion of on my car. It is missing the lower right corner. If this is any help, let me know and I'll send you a picture of what I have. The piece has no rust and is the proper gage of metal. my e-mail is w5sg@comcst.net
EMS are members listed on the HAMB as EMS customer service. They have a phone number in their profile for people to contact them. Regards
