Anyone know what these calipers fit? I bought these off fleabay because it said it was for 98-02 Camaro/Firebird. I have a 94 Formula but I’m putting on spindles from a 98-02 so I can upgrade the brakes later. In the meantime I wanted to use stock calipers, pads and rotors. These came in today and the brackets don’t match up with the spindles. Neither the caliper bracket is threaded or the spindle so they wouldn’t bolt up even if the mounting holes lined up.

I’m seeing online while trying to look them up that the PBR calipers were manufactured for OEM applications like the mustang cobra, corvette, and the SS. I guess my question is would these be worth hanging onto if I can get away with buying stock caliper brackets and they fit? Or should I send back and get the ones the idiot had pictured on the posting? I can’t seem to find PBR part numbers to see if they would actually work.

Appreciate any info or links. TIA
