Transmission Crossmember 1970-1974 2Nd-Gen F-Body LS Swap Transmission Crossmember For T56 (GM 4Th-Gen F-Body, Gto Versions Only) Hooker BlackHeart

Revised Design specifically for T56 (GM 4th-gen F-body/GTO versions only), T56 Magnum, 4L80E/4L85E, TH400 and 200R4 transmission installations. The revised design is easier to install since the feet are removable and can be installed separately. This crossmember is designed as an integral component of the complete Hooker Blackheart LS swap system for this vehicle application. Its unique design geometry is designed for compatibility with Hooker Blackheart 12512HKR and 12613HKR engine mounting brackets only. Due to design variances in the crossmember mounting hole locations on GM 2nd-gen F-body subframes, the mounting holes in this crossmember may not line-up directly with the mounting holes in your subframe. In such cases, the crossmember will need to be mounted using angle brackets included with this crossmember (requires drilling new holes in the subframe). * 4L80E/4L85E transmission installations require the use of a Hooker Blackheart 71223013HKR adapter bracket; TH400 or 2004R installations require the use of a Hooker Blackheart 12650HKR spacer kit. Note: this crossmember is not compatible with Tremec TR6060 transmissions. Provides for direct installation of a T56 (GM F-Body/GTO LS versions only) or T56 Magnum transmission. Provides for installation of a 4L80E, 4L85E, TH400 or 2004R transmission with the combined use of a Hooker Blackheart 71223013HKR adapter or 12650HKR spacer block. Designed specifically for use with Hooker Blackheart 12512HKR and 12613HKR engine mounting brackets. CAD modeled design optimizes fitment and strength while minimizing weight. Built with powder coated steel construction for attractive, long-lasting durability. Designed to provide optimized U-joint working angles and exhaust system ground clearance. Bolt-in compatible with all Hooker Blackheart headers, exhaust manifolds and exhaust systems available for this vehicle application. Designed for use with 71223029HKR (black) or 71223030HKR (red) transmission mount. Revised Design for easier installation with removable feet.
