Hooker Blackheart transmission adapter is part of the most comprehensive line of GEN-3 Hemi swap components available for the Mopar B-Body. The BHS535 crossmember adapter plate allows the installation of the popular NAG1 6-speed automatic transmissions when used with the BHS532 Transmission Crossmember. The BHS535 Adapter Plate bolts directly to the OE (Original Equipment) transmission mount location with the supplied hardware and eliminates the daunting task of figuring out correct drive line inclination and U-Joint operation angles. BHS535 transmission adapter plate is designed for use with GM style transmission mount for its compact design that allows for better ground clearance than the OE crossmember (use w/ Hooker part # 71223029HKR or 71223030HKR - sold separately). Solid 3/16" Steel construction and black coated finish provides long lasting performance and good looks.
