DC chin spoiler- asking before I drill!! :)

If my memory serves , Duster/Dart Sport was the last model to get the shock mounted bumper at the front. That car would have had the Y brackets, same as earlier models. Every other A-body got the shock mounted bumpers for 73.

Thanks! That's good info.
These cars were holdovers from a bygone era...in a good way. :)

I seem to recall that they were one of the last to get catalytic converters too, no?
