A body? B body? Throw away parts?

I need some help here guys... Going through and building out my front end on my 70 RT Challenger and these are the parts I had left over. The guy that sold me this project had a 68 duster GEN three that he had finished up rather nicely, so I'm guessing that they went to his car? The base of the spindle is 1.375 inches which is bigger than the 1.250 inches on the RT. Plus these discs, calipers and dust shields that do not go on a challenger. I'm tempted to throw them in my Scrap Metal bin due to the fact I have a really nice and honest scrap guy that comes by once in a while. However, I know some of these original spindles are getting hard to come by, so I'm not sure what to do or if I could make a buck off of them. Thoughts?

I think the original anti-rattle wire clip is worth keeping, the aftermarket clip is a bit different.  Someone with a 1971 and later A, B or E body may be interested in the calipers and related mounting hardware?

Good call. Thank you.

Those Kelsey Hayes 86166 calipers may not be "correct" for a 70 E-Body, but they can be used in place of the correct and hard to find 80012 calipers.  They would also be correct for a 71 and up E-Body.

I have a couple sets of the 80012's that have been fully rebuilt by Brad at Brake Warehouse in Minneapolis. The 4 86166 were laying around in my extra parts area that I'm always trying to thin out.

These definitely have value, don't throw them away.  These may be mid 70s spindles and calipers with early 70s rotors. There are still people interested in picking these up. If they match the specs in the picture below, these can be used for any disc conversion on any A, B, or E body. If they match these dimensions, you can also put the later model unicast rotors on them and get rid of the two-piece units. If this is what they are, I would buy them from you, but I fear shipping would be ridiculous.

H @HP2 great info! And your photo dimensions depict EXACTLY what these are!
Also, their mated disks appear to have only slight wear and no serious grooving. One mics out at 0.960 and the other at 0.990". Both of the dirt shields are in very good shape. So after learning this, perhaps I should hang onto them in case I ever switch to the Unicast rotors you mention?

Are the wheel studs 1/2" or 7/16"?  I thought all A-Body were 7/16 but then again I haven't studied those much.  Just curious. Either way I'm glad your not scrapping the parts.

avatar_mtull @mtull I just checked for you. They mic out at 0.500".

Since you verified the spindle and stud dimensions, definitely not junk. This is the core package for a disc brake conversion to any A,B,E bodied car. All it's missing is the prop valve and master cylinder.

Definitely worth keeping for a future project or selling to make back some bucks.

Agreed; I looked for a set of those spindles for quite a while (I'm not sure I trust the aftermarket made ones since I've heard that some counterfeits were actually castings instead of forgings, and could break). 

Presume those are the 1973 - 76 A-body spindles from the discussion; I have 1972 B/E body disk spindles to replace the OE drum spindles, the earlier ones have the smaller diameter inner bearing size; to use the later large bearing and later unicast disks they make a bearing spacer, but a solid spindle is definitely a better option.
