I needed rear calipers and I figured I'd be best off buying new.

Rockauto only has new calipers from a brand called ULTRA-POWER their part numbers are 191904 and 191905.

The parking brake won't work on them, minimal resistance in the handle and it won't stop the car from rolling at full engagement as seen from the cam pawl.

They didn't copy or machine the parking brake cam bolt and pill connecting rod properly.

I was able to swap the cam bolt and pill connecting rod from my old calipers into these to make them work.
