Anyone made an observation on the rear bumper bolts on early car?When I took my car apart the rear bumper bolts didn't have the large cadium washer with sealer on them.My bolts had much smaller flat washer and lock washer on each bolt.The rear brackets had green paint marks on backside of them also so guess what I'm asking anyone else seen this configuration?My bumpers are still original date coded also that looks like a stamp or something on inside also.Car is 7/64 Dearborn car as I know that's question is coming.
