Need help identifying this spindle

I bought this not knowing exactly what I was looking at while at Carlisle. The guy thought it was for an a-body disc brake set up as he had a 68 hemi dart in the past but he couldn't remember. I was going to have it as a spare for a 71 disc brake set up on my demon and thought they were the same. Wrong! Anyway, I don't see any numbers on it other than 18 70 83.

The guy only had mopars and specifically said a-body but did the hemi cars have a different spindle than 68-71 set up?

Does anyone recognize this spindle by chance at least so I know what it goes to?

I didn't pull any measurements, but I can on Tuesday if needed.

Thanks in advance,
Carl

Looks like a standard drum brake one to me. Give me a few and I'll run out to the shop and dig out mine. But i'm 80% sure those are drum brake ones
