From the article I got it from some corral website. The link started in 2.3 forum for the newbies for upgraded brakes
Rebuilt 73mm loaded pair calipers from a 1986 Lincoln. $125 list, I paid less. RMC part # P143. According to the auto parts store, all the mid-'80s Lincolns use the same calipers. They had the same part number for all of them. These loaded pair calipers came with steel pistons (better than phenolic), semi-metallic pads, crush washers and caliper pins. The pins have hex heads, not the dopey Torx heads.
