These are from a 1972 Skylark/GS Grill. I know they're different than 1970 as well as the 1972 METAL Grills but may be the same as the 1971 GS/GSX Grill?? (IF some one knows for sure if they're the same please chime in) Otherwise I'll check tomorrow as we have one in the shop that I can compare to. Fits 1972 Skylark, GS & GSX for sure with the Plastic Grill! These have been cleaned and bead blasted. $35 Shipped (U.S. 48) Correct Flange Nuts also included!
