The hood hinge bolts that attach to the apron are silver cad on all the models I have seen just like the fender bolts, however I noted on one of my cars the bolts are a little shorter than the fender bolts but made by the same fastener company. I have seen a few variances on the hinge to hood bolts, most have a cad. plating but are shorter and have a larger washer than the fender bolts, again several variances for sure.
