1963 Valiant Fender For Sale
I have a 64 fender on my 63 Valiant. They are the same except the 64 has a piece of sheetmetal spot welded to the headlight bucket. I drilled out the spot welds and removed that piece. I'd guess you could run a 63 fender on a 64 by removing the 64 piece from the old 64 fender and spot welding it onto the 63 fender. Externally, they look the same.
The hairpin on the 64-65 Barracudas and 65 Valiants is noticeably smaller than the 63-64 Valiants, so the fender for sale would not look correct on a 64-5 Barracuda or 65 Valiant, or match the stock fender on the other side.
