Wheel 102
Rallyu wheels covered, but what he might have is Magnum 500 or road wheels.
Magnum 500 was all chrome, and road wheels used the trim rings. if you are lucky to find stock Ford magnums you will find that they are wider than the Mopar ones. centercaps had some variation, but I am not certain as to what they were. mostly I just see stick-on replacements for these.
the rally wheels (acorn shaped centers) also had a set that some type of pop-in centercaps I have see plain and i have see some type of logos but could not tell you much more.
Good luck (any 103 classess out there?-lol)
