they have been put in a 63, but the guy didn't give me any pictures to prove they fit as good as the 64's did. the kick panels I modeled it off of was a 63 also but I didn't have any in my 66 to begin with so I tookl whatever parts I could find at the time and was available. I can mod a new mold up pretty quick if it's just the outside shape that's off (but ya gotta send me a tracing). If you need different ones, just let me know.
