1973 Duster

I’m not 100% sure of this but I have owned both styles of front ends. Just try a bumper swap to see if it bolts up to the older brackets. I think it will. BUT! Once you have all the parts for the conversion, it should just simply bolt together. Earlier bumper brackets if needed should not be to hard to find. (Here or on the net.)

For the most part, the mounting points don’t/didn’t change over the years, just the shape of the metal that bolts to it.

Welcome aboard!
