SALE PENDING New sill plates, I have (2) left hand side GM #7753967. They fit the Buick 70'-72' GS/Skylark. I think you could probably put lefts on both sides, but I am not selling these as a matched set. I am selling them seperately. For $45 each shipped. if you want both I will sell for $75 shipped. Within the 48 states. Also found a real nice toe board/carpet holder, not sure what you call this thing. $15 shipped
