good idea or bad idea?

to use brakes from a pick n pull salvage yard? obviously I would put new pads on them

they would be coming off a gp that is a 1999 or 2000, maybe even impala of similar year, could not find any gp in the 04+ range, I would find the ones with the least amount of rust on them

I was thinking of getting these, sand blasting them, then powder coating

just getting tired of doing the yearly paint job on the existing brakes with the dupicolor paint kit

edit: just thought of something else, the parking brake is different on the 04+ isn't it? so I might only be able to do the fronts this way
