The BMR transmission conversion crossmember for 1984–1992 third-generation F-Body applications is built to accept TH400 transmissions and gives a direct mounting location for swaps. Finished in black hammertone, it replaces the stock crossmember to secure and position the gearbox accurately, aiding driveline alignment and simplifying installation for projects converting to this automatic transmission type.
