Got it!

Kinda rough shape, but beggars can't be choosers.

Donor was a formerly V8-equipped single circuit Amazon, three piston calipers.

The rotors are rusty, filthy, but races and bearings looked good. Should turn okay. Couple of the studs are iffy, but we'll see if they can clean up.

The pads are practically new thickness, I'm planning to burnish them and call it a day.

The hard pressure lines (from top of the backing plate to the calipers) are in bad shape. Is that a DIY fab or are they available new/aftermarket? Or will I need custom lines anyway?

The caliper hardware looks iffy, I hope it will clean up. Are the pins and springs are available?

Best rebuild the calipers while I have them off, too.

Inner dust shields were destroyed in removal, gonna need those as well.

Swedishtreasures blacklisted me for returning parts, so I could use some help sourcing.
