Description

Fits 1979-1988 Chevrolet Monte Carlo; Transmission Crossmember-G-Body-LS - 12644Making 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. Due to the unique design geometry of this transmission crossmember, attempts to install it with headers and or engine mounting plates brackets other than those developed by HOOKER for this

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. Due to the unique design geometry of this transmission crossmember, attempts to install it with headers and/or engine mounting plates/brackets other than those developed by HOOKER™ for this application will more than likely not be successful. When used with the related Hooker™ 12643HKR or BHS5179 engine mounting bracket kit, this CAD designed transmission crossmember will replicate the stock small block Chevy engine/transmission inclination angle and eliminate or minimize the need to adjust the rear pinion angle in stock to moderately lowered chassis applications. Depending on the transmission, the following part numbers will be necessary: *No additional adapter needed for TH400/200R4/T-56/Magnum. TH350 Transmissions can reuse the factory transmission crossmember, but the slots in the center of the crossmember will need to be elongated in the forward direction. 12655HKR - 4L60/65/70/75 Transmission Adapter 12656HKR - 4L80/85 Transmission Adapter BHS5181 - 10L80/10L90 Car Transmission Adapter - must be used with BHS5182 (for G-Body) BHS5182 - 6L80/90, 8L45/80/90, 10L80/90 Transmission Adapter BHS5183 - Tremec TKX 5-Speed Transmission Adapter


Features:

  • 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

not better than manual……!!!!!
Do Not Buy This Product. this review is coming at 1 April 2026. This can opener was purchased in October 2025. My initial review was that it worked well and did the job. It was meant to do however, after a few uses, I noticed that the can opener continue to move around and around the can even after the can lid had been cut open. in January 2026 it began to make more and more rotations around the can and the lid was not cut loose. After a few more uses. It just rotated and did nothing else. I sent an email to the company. I contacted Amazon about it. I’ve done everything that I can possibly see to do but I get no positive results. Consequently, I have a six month old can opener. It does not work. worked well for the first 10 or 20 uses; then the cutting edge just wore out (3-4mos.), so now my money was wasted. No explanation no offer, too bad.

Don't waste money on this one
Ordered in January 2026. Worked good the first few times. Now it just rotates around and around the can but doesn't cut anything. I'm so disappointed because it failed shortly after my return window closed.

Easy to use! No more hand cranking.
If you like the ease of an electric can opener, but don’t have room to store it or don’t want to drag it out when you need to use it, this is for you. I like a handheld can opener, but would get so frustrated trying to use it and turn the handle. This can opener is amazing and so easy to use. Just attach to can and push a button. It starts turning on its own and when it is done it stops. You lift it up and the lid comes off cleanly. It is rechargeable so need to worry about batteries. It tucks away in a drawer nicely. I bought my mom one too. She has arthritis in her hands so thought this would be perfect for her.
