I'm set on the Studs,(have 100!) "special" made to fit the original '68 bracket holes, press in, no glue, weld, etc. required, pretty much exactly like the original head too (flat) no grinding required.
Difference is they are stainless steel, and do not have the special "tip". (to make it easier not to cross thread)
Thanks! Good Info for repair options! I didn't realize '67 holes were square!
If I make up some sort of "Kit" may have to title it:
'68 (ONLY) Barracuda Grill surround "Stud Repair" and "Assembly" Kit
