So i have researched all the threads on this topic and am looking for some clarification. Many years ago I pulled the bumper off my '73 because it was not repairable and it was thrown away. Sadly the brackets went with it as well. This weekend I picked up what I believe to be off of a '74 from a wrecking yard which is nice and straight and will work well for my purposes. Unfortunately with out brackets from either car I can't tell what year it is off of. Does anyone have pics of the brackets/inside the bumper shell of a '73 vs '74? I was this is a 74 because inside the bumper shell there is a bracket or brace that runs the whole length of it. If I recall correctly my original brackets were two smaller individual pieces.
