BMR's transmission conversion crossmember for 1998–2002 fourth-generation F-Body vehicles is engineered to accept TH350 or Powerglide automatics with an LS1 engine. It replaces the OEM stamped-steel crossmember with a stronger, correctly located fabricated unit to simplify swaps and increase reliability for street, drag, and handling use, while keeping installation straightforward for common transmission conversions.
