8 3/4 rear disc swap - ford ranger/explorer

The"backing plate" is all one piece, which contains the caliper mounting bracket. The first photo shows where you have to drill the 5th hole. The second photo shows the different kind of emergency brake cable. On regular drum brakes, there is a ball on the end of the cable. On this setup, it's a squared eyelet that goes over a hook. I haven't figured out how to deal with the e-brake cables yet, mine were cut off. I think I'm going to go to the junkyard and scrounge up a set of cables, then figure out how to hook them up.

That's very helpful, thank you!. Did you have to modify anything beyond wheel studs? Like opening the Center bore? Or you just drill the missing hole and done? Went on like stock? (Not worried about e brake)
