1968 XR7 from Dearborn, I have seen in the catalogs, phosphate, cadium or black. Some are stamped RBK and some SMS? the ones on my car look like maybe they had a T on the head of the bolt but that is it. Not sure what I would call the color of them. I have been looking at buying a complete body kit from AMK. What is the correct color or type of bolt for the fenders? And would the kit from AMK have the correct ones?
