Early Discs? Not mine on CL

Those are late model calipers. Probably spindle too. Or some Mickey Mouse Hybrid of the two.
 
"They were pulled off my 1974 Challenger project"
maybe F-Body?

Don't you just love it when somebody interferes with your ad, your posting, when they don't know what the F they're talking about in a reply.
You have your parts listed accurately.
1970 -72 B & E body disc brakes used the smaller diameter inner wheel bearing that you advertised correctly about your spindles.
You have pin type caliper brackets, so they were used on the 70 74 E body's, and 70 72 B body's.
You DO NOT have "F" body brakes.
Those have a different machined, styled, spindle, than B or E body ones.
You know what your looking at, once you've been around the cars for decades.
And the 73-76 A body car, disc brakes, used "Slider Type" calipers, which you don't have in your pictures.

I Hope you don't think it was my ad!
I'm not up on brakes, The " " means I was quoting what the person said in their ad. I do know my 70 barracuda had F body front disc brakes on it so I was wondering if they were F body since he said he pulled them off his challenger. I happen to be keeping an eye out for disc brakes for one of my early A's and had wondered myself at was was listed.

Ok then.
The owner of the parts, has them advertised accurately.
Small bearing, inner wheel bearing, makes them 70-72.
 
Not mine but I did post it. I'm no expert but thought someone could use this stuff.
Ya, that's ok, but these days the 70-72 spindles aren't that desirable anymore, due to the availability of rotors needed for those spindles, due to cost.
But in the guys picture, it appears that one of his calipers is the "wide mouth" design which was 1970 only.
And those are high $$$$$$$ items, these days.

Looks like 2 different spindles, if you look at the one it has a bigger inner bearing than the other.

You can tell that from the picture??
I can't.
My eyes ain't that good, in my old age. :rolleyes:

Then, i will open up this thought.
The wide mouth caliper, belongs to the 70-72 small inner bearing spindle, and the other spindle, and caliper would be a 73 74 E body spindle, large inner bearing.
A mix matched parts set up.
So then, without measurements, and an in person inspection, who the hell knows.
 
You can use 73 and up rotors on the 70-72 B&E body spindles by using the bearing adapter that DR. Diff sells. Jim is right, in that the 2 piece rotors for the 70 - 72 spindles cost out the ying yang. They also have a tendency to warp to hell and back. When I get around to fixing my 70 Challenger 340 that I have owned since 1979, I will be using later rotors with the rear bearing adapter. Front (outside) bearing is the same for both types of rotors.
