Just to help, this would be the lower skirt rim on the 1963 6039 (Fleetwood 60 Special) and 6367 (Eldorado Biarritz). Different from 1964 6039. I've got the 64-6039 lower skirt trim but not the 63-6039.
Bob, since you just want the fender skirt trim on your car, the trim from any year mentioned will work.
I have one piece of the 1963-only Eldorado and Fleetwood 60S ribbed stainless fender skirt trim. I think it is for the front portion of the LH side, but I'll have to get it out and check. Send me an e-mail to email@example.com and I'll send photos.
Just to be clear, the 1963 6039 & 6367 Fender Skirt is a 2 piece skirt. the front small lower section is separate. The 1964 6039 skirt is a one piece skirt and is shaped differently. If you want the 1 piece 1964 6039 Skirt, I have the left driver side from an 41K mile 64-6039 I pulled in about a decade ago. The price is $75. I do not have the right passenger side.
