Rear disc brakes

[swappy]

I am cutting out impala bracket next week. But I was wondering if any one has dimensions for the camaro caliper bracket. I would like to make my pickup street legal. In addition to that question I was wondering if any one had has used Newer, better technology off something like a 200? monte impala vette or another gm car or truck. Even info on setups that would or did not work could be useful to me or somebody else.
