brushed 15" trim rings showed up during the run of Superbirds (I think Chrysler was trying to save a few pennies on a car they were loosing $$ on each unit)
they returned for the AAR & T/A as STANDARD equipment
and were STANDARD for 1971
So you are saying Brushed for all Superbirds? No polished for Superbirds?
early W21 F60-15 Superbirds polished #34610
43 &
late W21 F60-15 Superbirds brushed #34612
22GG's "white book" has the change before/after 12/10/69 production
so ..... Superbird #1679 RM23V0A170843 arrived at Clairpointe on 11-Dec & departed on 12-Dec ..... it is going to be right on the bubble - What do you know about its original wheels/trim rings? Is there a broadcast sheet?
