60 - 62 Valiant / Lancer Source?
You should try Slant Six . Org. Lots of 1st gen Lancers and Valiants over there. Also Wildcat Motors in Oregon? Pricey, but they have inventory. Lee Robinson on here has parted a few also, maybe he has something. Also on Ebay I see a yard posting various Lancer Trim, don't remember the user name. Search and then check completed listings, maybe you can find them.
