Anybody recognize these spindels? large brake caliper

Going threw my extra brakes set ups and I ran across these. I just can't remember what they came off of and the spindle look quite a bit differnet from any of the others I have. Anyone recognize them??? They use the larger slide calipers. Thanks for taking a look

My guess is C-body.

Definitely looks like C body... Could by 73.... Any markings?

I'd like to see a better picture, but that looks like F/M/J body. They had the lower ball joint in the control arm with the stud going through the steering arm as opposed to being part of the steering arm.

I think FMJ has a shorter steering arm...

This is the front side. takes the 11.75 rotors so I thought cordoba but those use the dart size calipers. these use the larger truck maybe?

I will go look for numbers. and get another and get more pictures of the back.

Dust shield is NOT FMJ.

Dust shield not 74 b-body, 73-74 b-bodies used pin type brake calipers and have a shorter steering arm too.

Looks like the set up I took off a B200 van in hopes of using them on my 67 Imperial.

if it's a 1" wide rotor, late B? 11.75" rotors became standard on the late B/R's ~'76 or so.

if it's a 1.25" wide rotor, I'd wager truck or C body
