I found them in it, not on it , guy said they weren't original, but I didn't ask him if they came with it when he bought the car, he felt as I did that the car wouldn't have these on if it were factory, but there was a lot of dealer installed or catolog parts in this car , so it is possible they came with it, but its pretty oxidized, I got the make of some numbers on it, but its a tough read so far, whats an example of a 67 or 68 date code on these
