Not mine. They look pretty decent. https://www.kijiji.ca/v-auto-body-parts/barrie/1970-buick-skylark-bumpers-nos/1491910060
If they were NOS it would be a deal, but alas they are not. I don't think the seller knows what NOS means.
If they were NOS that would be a STEAL of a deal!! In this case I think they're overpriced as cores, even in US dollars.
In this case NOS stands for Nasty Old Sh#! I bought my front 70 bumper on the board years ago for $285 shipped. It is used and in far better shape than these. (Ty Eric6659) Jim
He probably meant (or should've used) use the term OEM. In any event parts for these old cars are hard to get up here as we don't have the abundance you guys got so someone will buy them.
