For those of you who are interested in getting as close to an original appearance as possible, Totally Stainless sells some black-anodized stainless-steel hardware. Their black recessed-head hex bolts look just like the original bolts used to attach the inner to outer fenders in the engine compartment (and the black recessed hex-head bolts/screws that attach the radiator shroud to the top of the grill and the top of the radiator).
