What are they called?

[Mopar-Mitch]

The brackets that hold the headlight buckets and adjusters on 70-72 darts and demons, these unbolt and aren't spot welded like 67-69. Also will these be the same on any other cars like 73-76 dart? I can't find them reproduction and they dont come on the new repro dart fenders. I'm looking to build another car in the future and I'm trying to collect parts I will need if I buy new front fenders for it.
