Need help with brake caliper I.D. please

[frozennorth]

Could you help me with these.  They were on my 71 Duster.  I should either rebuild or replace them.
No idea where they came from.  The inside diameter is about 2 1/8"
Some numbers on them are 3019,   781,   E252.
Think I'd be lost without you guys


Thanks

They look like 73-up a-body (F/M/J body, too).

Yep just your run-of-the-mill big bolt pattern slider type calipers.

My Satellite had that type (slider) but my '74 Duster stuff has the bolt and the springy type clamp on each end.

Now, can I just order later duster calipers or should I order a different
body style?

Thanks
