How much will those run? I can get some for $14 each and want to see if your prices will be comparable.
Went to John's Mustangs in Houston www.johnsmustang.com and looked at all the brackets they have, and these ended up being the correct ones even though they are listed in his catalog for 69-70 models. Only $14 each But, like always, I HATE dealing with those people. Unless you get the kid behind the counter, the older workers are very difficult to deal with. Had to argue with the old lady that the first set she brought out were not the right ones. She wanted me to bring my car in and prove it. Finally she gave up and let the kid go get the other set, and they were right. She still argued that I had the wrong year model car Anyway, these are them for $14 (picture us of the bottom, not the typical angle you see of them) http://johnsmustang.com/Parts/details-6659.html
