The bolts/screws (in the engine compartment) that hold the inner fender to the outer fender, and the bolts that hold the cover at the top of the grill (in front of the radiator - the grill/radiator shroud?) were, I think black with recessed heads.
Totally Stainless sells those recess-head bolts/screws in a black anodized(?) stainless steel.
