Greetings everyone. I'm doing some final detailing on my 65 Tempest custom sports coupe ( 326 ) and looking to find out what the correct fastener head markings should be for the radiator core support bolts. I'm most interested in the hood latch release , upper radiator support bracket and the fender to core support bolts. Inline tube says the anchor marking is correct for 65 however Ive been to several shows and I don't see any 65 GTO's with those markings. I can't find anything in any manual or pictures of survivors showing whats correct. My car did not have original hardware when disassembled. Any help and or pictures will be appreciated.
