I might warn you and others that if you have Spectrum in this area you might have to break out a chisel in order to whack at the Spectrum to get this bracket to fit.
If you install the bracket before you add the sealer it will be easier on those years and plants where the bracket was installed pre paint.
Surfaces would have received a couple of coats from different directions. From the door jamb side when the door edge and hinges were painted and when the end of the door and a pillar was painted body color next
There is a lot of paint in this area. Red oxide, black on bracket, then primer, exterior paint and then possibly black when you paint the front clip semi-gloss.
Not certain that the light gray surfacing primer was applied after this bracket was added.
Engine compartment and wheel well black would not have normally gotten close to this area of the car at San Jose or NJ - especially Dearborn on either year.
