HOGDADDY; I have an "early" (11A -66) '67 Coupe, and it has the 4 Sub-frame bolts like you pictured in your original post with the indented head and shoulder washer, and pointed. These 4 are 5/8 in. X 3 in. long, I believe the Core support bolts should look the same, except they are only 1/2 in. X 3 in.. I believe mine are all original to the car. I'm seeing all Repop's of the Sub-frame bolts with No indented head, No shoulder washer, and no Point on the other end - and they are claiming these correct, so I'm wondering if they changed somewhere along the way. Good luck sorting this out.
