1982-1992 GM F-Body:
If you have a Spohn transmission crossmember mounted torque arm and you're now converting to a different transmission you can buy just the appropriate crossmember. All of our crossmember mounted torque arm kits are the same with the exception of the transmission crossmember. If you're swapping transmissions just select the crossmember you need at this link.
1993-2002 GM F-Body:
Our Part #402, 402-PS, 405 and 405-PS use the same style torque arms, only the crossmember is different.
