  • Fits Models: GM RWD G-Body; Malibu, Monte Carlo, El Camino, Cutlass, Grand Prix, Regal, Century, LeMans, Caballero, Bonneville
  • Fits Years: 78-83
  • Fits Transmissions: TH400, 2004R
  • If you are looking for improved performance check out our lighter weight, next generation of this crossmember,  RCGNG-400KBLK.
  • We recommend a polyurethane transmission mount. The G Force  GMTM is sold separately.
  • G force has developed a frame extension, GF-FE100, to duplicate this longer frame on the early generation vehicles. The RCG-400K is pre-packaged with the frame extension.
  • The primary frame change on the 1978-1988 generation of GM G-Body vehicles begins with 1984 models and the implementation of the 2004R transmission which required positioning the crossmember further to the rear of the vehicle. This is evidenced by two sets of frame holes for the crossmember on the driver side of the vehicle.
  • Note: Some 1983 Hurst Olds are known to have the 2004R transmission and thus the longer frame rail which does not require the GF-FE100 frame extension that is included in this Kit.  Some 1984 El Caminos retained the early frames and do require an GF-FE100 frame extension to run this crossmember.

Very nice but...
Color: B-brown
It's a beautiful bag but the outside zipper pockets are deceiving, they're very small . My phone couldn't fit inside. No bad smell, the organization inside is good and the strap length is pefect. Because the outside zipper pockets are too small I may have to return it.

Good quantity
Color: A-shiny Brown
Perfect size for me. The different compartments makes it easier for organizing. Has a mild order but after turning it inside out and put it in the sun for a few minutes, problem solved.
