Part # 12644HKR-1

• This LS and LT Swap Crossmember for the GM G-Body has some very minor design updates & has been updated from 12644HKR to part number 12644HKR-1
• Facilitates installation of a 4L60/4L65/4L70/4L80/TH400/2004R/T56/T56 behind an LS engine in 78-88 GM A/G Body applications (may require add-on bracket, see installation notes)
• Designed using CAD modeling/FEA analysis for optimal fitment, strength, weight, safety and appearance
• Welded steel construction
• Provides an optimized engine/transmission inclination angle that is critical to obtaining suitable U-joint working angles, when installed with Hooker 12643HKR engine mounts
• Designed in conjunction with other Hooker BlackHeart GM A/G-Body engine swap brackets to provide bolt-in installation of Hooker LS swap manifolds, headers and exhaust systems for this application
• "Provides the highest clearance available for up to 3 dual exhaust system routing"

Making it possible to fit almost any GM transmission into your G-Body alongside an LS or LT, this updated transmission crossmember should be used with an aftermarket urethane transmission mount such as the Hooker Blackheart 71223029HKR or 71223030HKR or equivalent.
