Sorry guys I think I have caused some confusion with my hasty review of Jeff's comments. I didn't notice the red arrow pointing to the bracket in the photo. I work as a structural engineering detailer and refer to everything that's not cast as plate steel regardless of the finish. The face bracket had blue paint on it that came off very easy just with solvent, almost flaky. I didn't see any evidence of any other color underneath the blue. The bare metal looked like it could of been phosphate. Wonder if some one did some touch up at one time and sprayed over it. The alternator bracket also had silver paint on top of black and it also came off very easy. Thanks for the help I really appreciate all the great advice.
