i just sold a rear disc setup on ebay that i fabbed up using 98-01 Camaro rear disc components... i changed out my rear axle with one from a Chevelle, so i now have a 5x4.75" pattern on the rear... ended up going with a setup from a 93-97 camaro - 11.5" discs instead of the 12" discs from the 98-01
