Anyone tried installing a disc brake setup on a GN? Supposedly, a 93-97 Camaro or Trans-Am rear disc setup is a direct bolt on but my local brake shop mechanic has said there is a problem with the drum backing plate being welded on and the rear disc backing plate being a bolt on. I thought if that was so then perhaps I could cut the drum backing plate and have the disc backing plate welded on but I wanted some insight before taking the cutter to my rearend.
