Ok, so I finished upgrading my Challenger to Magnumforce drop spindles and 11.75" brakes, so this stuff is for sale. I'm in Sacramento, CA, and can take Paypal.
1972 E-body spindles- these use the earlier (smaller) bearing type. These are originals, with roughly 100k miles on them, but no damage. They are dirty... I see the later ('73 up) go for $150+, but they're more desirable. Lets say $100 +shipping OBO, I'm flexible on these.

1972 1 piece replacement rotors. These replace the original 2-piece type and came from AutoZone. They've got about 2,000 miles on them, but still measure right at 1" so no real wear. No gouges. I paid $160+ tax, I'll take $100 + shipping. Probably only worth it if you're on the west coast, I should be able to ship them for ~$40 bucks within about 500 miles (that's what the 11.75 rotors I bought cost to ship...). You'd still save over $30 from Autozone with that shipping.
10.98" caliper brackets, pin type. Stock for E-bodys. Nothing special, not the best style caliper or bigger than stock. Original, $50 +shipping OBO
I've also got the wheel bearings for this setup as well, I'll throw them in with the rotors or spindles if you want them, whoever asks first gets 'em.
