A friend has some NOS stainless side trim pieces still in the factory brown paper. Do these part numbers sound like Ford numbers? FM 503R BG 7325556A another is FM 901 4647190 and the last is FM 510 BV16003C Photo shows the profile.
The first item is for '53 Ford fordor right rear quarter. The third item is for '54 Mercury left front fender. The second number is not a Ford part number.
