yes, those are what i have some of, a recessed area on the bolt head where the markings are. i have some with the NL & some with other letters like W or E & some with no markings. then i have some with the flat top like the 1st pic but other letters or no markings at all. these style of bolts were used on the oil pan too & i have a bunch of all variations but havent found a full matching set of 8 with the NL yet.
im still checking my other boxes of bolts but that requires a lot of digging, was hoping between what i have & what other members might be able to locate we could make a full set for him. & also to see what the other types pontiac may have used for these cars.
