Fits 1979-1988 Chevrolet Monte Carlo; Transmission Crossmember-G-Body-LS

Description: Fits 1979-1988 Chevrolet Monte Carlo; Transmission Crossmember-G-Body-LS - 12644 SKU: 12644HKR-1 Brand: Hooker BlackHeart Condition: New MPN: 12644HKR-1 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-1Facilitates 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 appearanceWelded steel constructionProvides an optimized engine/transmission inclination angle that is critical to obtaining suitable U-joint working angles, when installed with Hooker 12643HKR engine mountsDesigned 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 applicationProvides the highest clearance available for up to 3" dual exhaust system routing Specs:BrandHooker BlackHeartColorBlackEmission Code5EngineGM Gen III/IV (LS)FinishBlack PowdercoatedMaterialSteelProduct TypeTransmission CrossmemberSale CategoryEngine Swap PartsTransmission200R4Transmission4L60ETransmission4L65ETransmission4L70ETransmission4L75ETransmission4L80ETransmission4L85ETransmissionT56 GMTransmissionT56 Magnum GMTransmissionTH400Type of ComponentCrossmember Application:YearMakeModelSubmodel1979-1988ChevroletMonte CarloBase1986-1988ChevroletMonte CarloLS1983-1988ChevroletMonte CarloSS1978-1988OldsmobileCutlass CalaisBase1988OldsmobileCutlass CalaisGT1988OldsmobileCutlass CalaisInternational1988OldsmobileCutlass CalaisSL1982-1988OldsmobileCutlass CieraBase1982-1988OldsmobileCutlass CieraBrougham1988OldsmobileCutlass CieraInternational1982-1988OldsmobileCutlass CieraLS1986-1988OldsmobileCutlass CieraS1986-1988OldsmobileCutlass CieraSL1978-1988OldsmobileCutlass SupremeBase1988OldsmobileCutlass SupremeClassic1988OldsmobileCutlass SupremeClassic Brougham1988OldsmobileCutlass SupremeIndy 500 Pace Car1988OldsmobileCutlass SupremeInternational1988OldsmobileCutlass SupremeSL1978-1988PontiacGrand PrixBase1984-1988PontiacGrand PrixLE1988PontiacGrand PrixSE1988PontiacLeMansAerocoupe1988PontiacLeMansAerocoupe YL1978-1988PontiacLeMansBase1988PontiacLeMansSE1988PontiacLeMansValue Leader1978-1987BuickRegalBase1987BuickRegalGNX1984-1987BuickRegalGrand National1978-1987BuickRegalLimited1978-1987ChevroletEl CaminoBase1978-1987ChevroletEl CaminoSS1978-1987GMCCaballeroBase1978-1987GMCCaballeroDiablo1980-1987OldsmobileCutlassBase1987OldsmobileCutlassEurosport1987OldsmobileCutlassLujo1985-1987OldsmobileCutlassSalon1985-1987OldsmobileCutlass CieraGT1978-1987OldsmobileCutlass SalonBase1987OldsmobileCutlass Supreme4421978-1987OldsmobileCutlass SupremeBrougham1981-1987PontiacGrand PrixBrougham1983-1986BuickRegalT-Type1978-1986ChevroletEl CaminoConquista1981-1986GMCCaballeroAmarillo1983-1986OldsmobileCutlass CieraES1985-1986OldsmobileCutlass CieraHoliday1978-1986OldsmobileCutlass Salon4421978-1986PontiacBonnevilleBase1978-1986PontiacBonnevilleBrougham1984-1986PontiacBonnevilleLE1984-1985OldsmobileCutlass CieraCruiser1984-1985OldsmobileCutlass CieraCruiser LS1981-1985OldsmobileCutlass SupremeLS1983-1984OldsmobileCutlass CalaisHurst1982-1983BuickRegalEstate Wagon1978-1983ChevroletMalibuClassic1983ChevroletMonte CarloCL1980-1983OldsmobileCutlass CruiserBase1978-1983PontiacGrand PrixLJ1982BuickRegalLimited Turbo1978-1982BuickRegalSport1979-1981ChevroletEl CaminoRoyal Knight1978-1981ChevroletMalibuBase1978-1981ChevroletMalibuClassic Landau1978-1981ChevroletMonte CarloLandau1981GMCCaballeroConquista1981GMCCaballeroRoyal Knight1980-1981OldsmobileCutlassBrougham1980-1981OldsmobileCutlassLS1981OldsmobileCutlassSupreme1980-1981OldsmobileCutlass CruiserBrougham1978-1981PontiacBonnevilleSafari1978-1981PontiacLeMansSafari1978-1980ChevroletMalibuClassic Estate1979-1980ChevroletMalibuClassic Sport1979-1980ChevroletMalibuEstate1979-1980ChevroletMalibuSport1978-1980ChevroletMonte CarloSport1978-1980GMCCaballeroLaredo1978-1980OldsmobileCutlass SalonBrougham1978-1980PontiacGrand PrixSJ1979ChevroletMalibuLandau1979ChevroletMalibuPolice1978-1979OldsmobileCutlassVista Cruiser1979OldsmobileCutlassVista Cruiser Brougham1979OldsmobileCutlass SalonHurst
