Problems Identifying and Matching up new Brake Calipers

I've acquired quite a few older application books for a lot of stuff. I have a big EIS catalog, so I was able to find the 76 A body calipers on Ebay. These are new EIS made in USA calipers. A lot of those items are still available if you have a brand and part number. It's nice to buy stuff that has Made in USA cast into it.
