My calipers are Ford units from AutoZone... that's why they were correct. The upgrade was worth it, but if I had to do it again, I'd spend a little more money and do some research to get better calipers. Not those clunky, super heavy, flash-rusting units that are residing behind my clunky, rusted wheels.
I've since switched pads with the Moroso rotors. Lets see how these new Semi-Mets do. The first pads I used were ceramics. Not good with those rotors. They blued in a coupla thousand miles. Then I switched to whatever was laying around. Pads I had purchased incase the ceramics didn't work out. I had to remachine the rotors again because of groves from the cheap pads. Now, the pads that came with the loaded calipers are on the car. Hoping for the best.
I guess I think they're garbage because I don't care for floating calipers. These babies sure are better than the stock '91 units, though!
And BTW, I like the local parts stores b/c they are easier to deal with and -in general- they sell more quality parts. AutoZone won't give you Felpro gaskets, Gates belts, BCA hub/wb sets, and all the other good stuff I prefer to use. They'll just as easily sell a poor knockoff part made in china for the same price or a few bucks less.
Thanks to the boys at ACME Auto, Exact Auto, and Bethel Auto, I can get the parts I need. Often with discounts.
BTW, I had to go on a wild goose hunt for the mounting bolts that AutoZone didn't have. Nor did Advance, Ford, NAPA, or Levines. But Meeker hardware came through in the bind.

Advice: get ALL the parts you need first, and then start the project. I can't tell you how many times I ran to the parts store... 25 minutes away!
