I have 10 brand new valve cover bolts in a sealed bag that’s marked Mopar/Jeep/Ram etc but the heads are not mark “SEMA”. I found 5 or 6 used bolts with a “C” on the head. I might have some more used ones in storage but will have to check. View attachment 1715264751View attachment 1715264752
Can it be that Chrysler back in the day had more then one supplier? I have only found SEMA bolts but those C bolts looks spot on except the SEMA text on the head.
