ruff stuff makes brackets that work with gm metric calipers off the front of a 80s gm1500. the calipers are about 30 bucks from napa, brackets are 50 and you use bronco front rotors.

Not sure if you are interested/ or need a parking brake (bullshit stuff I have to think about to pass inspection out here) but you can pull the backing plate/disc assembly off 90s explorers and bolt them up with slight modification

Shows the general install process for the Explorer 8.8 brakes on a 9 inch. If you've got the Torino/late big bearing housing ends and the right axle face to bearing seat measurement, it's dirt cheap and easy with junkyard parts and re-drilled rotors.

Not worth it if you have to buy new axles to make them work though. Weld-on GM caliper brackets for sure at that point.

A couple tips:

Double check and make sure the calipers have room to float on the pins before you weld on the caliper bracket. Mock up everything, pads, rotors, etc. I did all that and still had a brake dragging problem. I ended up having to belt sand the brake pads down to allow the caliper to float.

Also, these brakes work very well. I would say a proportioning valve is pretty much mandatory to dial out rear braking. Without it, I had problems with the rear tires locking up first and wanted to spin around on me.

Afta all that, they have been great for at least 6yrs now

Also the 80's chevy calipers those brackets are made for are a metric 10MM banjo bolt and the same caliper from the 70's is a 3/8" Banjo bolt. Same size hole for brake lines but heads up you'll need banjo bolts for them as well.

Last thing I did when I used their brackets on a 9in is I cut a notch in the bottom edge so you can install/remove the t-bolts that hold the axle/bearing in just incase if gets buggered up.
