aluminum bumper brackets

Factory steel bumpers or fiberglass?

The original, steel bumper.

I just ran one bracket on each side with dummy bumper bolts in the other holes.

Factory 68 barracuda bumper brackets used a system of 4 heavy brackets (and 1 small tab at each outer end).

If you want more strength you could bend up all the brackets in aluminum and still be under 1/2 pound.

I have all the original stuff back on the car now.
