I recently purchased a 92 rs with the intent on drag racing it. after about three passes in it i busted the tail shaft on the trans and killed my ring and pinion. does anyone know of any bolt in ladder bar setups available? and will a 10 bolt from a 76 camaro be the same width as the 10 bolt in my 92?

your best bet would be to spend the money and get a moser 12 bolt or 9inch for the car. and an adjustable torque that relocates the arm from the tranny to the floor or crossmember.not cheap but its the best way, to my knowledge there is no ladderbar setup that will bolt up. you will end up back halfing the car.
