go to the nearest chevy dealer and see if they can get you the correct tailshaft housing.it needs to be hooked up- it is what hols the rear end at the proper angle. it is not just a slapper bar, it actually locates the rear front to back and sets the pinion angle.maybe you could fab up a mount to hook it up to the tranny crossmember somehow? i don't have a camaro, and am not sure how it mounts. but, if you have a welder and some skill,you could make some sort of adjustable front mount. that way, you could play with pinion angles and instant centers and make it hook hard or soft, depending on what you need.
