If your issue is radio interference (RF) then you can try what was suggest to A12 owners back in the day when the fiberglass hoods didn't offer sufficient RF shielding.......this is no lie, this was released I think by Chrysler Canada back in the day. My '69 A12's antenna and a few other A12's antennas were moved to the rear quarter panel/fender and Dutchman panel back in the day for the RF issue and complaints. That's the reason the fiberglass hood T/A and AAR antennas were placed back there the next model year. They could have just skipped the expense and lined the under side of the hood with aluminum ("tin") foil and been done with it
