Installing  a TH400 (4” tail shaft) automatic transmission into your 1982-1992 Camaro or  Firebird just got easier. This transmission cross-member with integrated torque  arm mount features the correct provisions for mounting the TH400 transmission  while still allowing the use of a factory style torque arm. The built in torque  arm mount will work with virtually any stock style aftermarket torque arm as  well as the factory torque arm and features instant center adjustment by moving  the front of the torque arm up or down. This unit is built using DOM mild steel  tubing, 0.188” mild steel mounting plates and includes all appropriate hardware  needed for the installation. The torque arm mount is machined from 0.250” thick  mild steel and features a new clam shell for appropriately attaching the torque  arm to the new cross member. There is no need to purchase any other torque arm  brackets when using this kit.
