Wayne Due made a bracket kit for around $1000 that made a mostly bolt in from a C4 Vette, however Wayne Due is out if business. There has been a few threads on Lateral-g and ProTouring that detail some builds, try searching for "Wayne Due Camaro" and "IRS" or "C4" and see what comes up.
I looked into this before I got the Chassisworks g-link, and on one of those threads someone was willing to duplicate the brackets. Sorry, your going to need search the archives and maybe even google on that one if you are inclined to go that route.
Found one thread....
