The factory rear end uses two long bolts that go through the top and bottom of the torque arm's rear mount. Our SKU# 982 torque arm mounting bolt hardware kit is for use on factory style torque arm mounting rear ends (anything but a Moser 12 bolt rear).
The Moser Engineering 12 bolt rear end for the 1982-2002 GM F-Body, Camaro and Firebird uses four tapped holes that are not all the way through. You will need to use the torque arm mounting bolts that are supplied with your Moser 12 bolt rear end to mount our (or any) torque arm to the Moser 12 bolt rear end's torque arm mount.
