Hooker BlackHeart transmission crossmember is part of the most comprehensive line of GEN-3 Hemi Swap components available for the Mopar B-Body. The BHS532 Crossmember allows the installation of the popular A727 3-speed, NAG1 5-Speed and 8HP70 8-speed automatic transmissions when used with the corresponding adapter plate (sold separately). No cutting or drilling is necessary, Just bolt it in the OEM location using the supplied hardware. The modular design allows the use of several different transmission options without the need to buy or fabricate a different Crossmember – simply change to a different adapter plate and the drive line and u-joint alignment have been preset to the corresponding transmission. BHS532 Crossmembers are designed to use a popular and inexpensive GM style transmission mount for its compact design that allows for better ground clearance than the OEM crossmember (Hooker part number 71223029HKR or 71223030HKR – sold separately). Solid 3/16″ Steel construction and Black coated finish provides long lasting performance and good looks.
