Need advise on finish for my coil bracket. I am restoring a 1966 mustang 289 hipo, August 12th (late car), Dearborn built car. I have read all of the threads in the library but am still confused which way to go. I have read that brackets could be PO (zinc phosphate) or semi-gloss black or even natural. What finish should I restore my bracket considering the date and build location. Thanks for the help.
