The appear to be correct for 69 and up. They are the same as 67-68 rims but in those years they were a lighter grey (argent) color. They weren't original , but I have a set on 68 KAT and they look GREAT!!!
These are correct for 1969 & 70. The 67/68 had no inserts, and were chromed or painted body color. I think the center hole is bigger in 69 & 70 rims. The paint on your rims looks a bit dark. Eastwood sells a color that is NOT correct, John Baumann (John's Cougars) is one among a few that should carry the paint, if you need.
