  • P/N RCG-400 installation notes:
  • On all 78-88 G body crossmembers, the passenger side hump is the taller of the two.
  • On some installations, it is necessary to remove the catalytic converter heat shield from the passenger side floor pan.
  • This generation of vehicle is prone to body bushing compression, even with some southern vehicles. If the floor pan is too close to allow installation, it may be necessary to replace the body bushings. Some customers have reported that with slight interference instances, they have been able to gently lift the floor pan with the assist of a floor jack and a wood cushion, thus providing the required clearance for installation.
  • The crossmember is installed so that the exhaust clearance humps are closed on the top and open on the bottom.
  • The RCG-400 is bolted to the rear set of frame holes on the driver’s side frame rail.

NOTE: Some 1983 Hurst Olds were delivered from the factory with the 2004R transmission. These 1983 models do not need a frame extension to run the longer transmission series crossmembers. (The early frame configuration as seen on most 78-83 vehicles has one location to bolt the transmission crossmember on the driver side frame rail, which is in relative close proximity to the drivers door hinge. The late frame configuration as seen on most 84-88 vehicles has two locations to bolt the transmission crossmember on the driver side frame rail, with the second location approximately 14″ rearward of the front set.)

NOTE: Some 1984 El Camino’s were delivered from the factory with the early style frame configuration, and WILL NEED a FE-100 Frame Extension to run the longer transmission series crossmembers. (The early frame configuration as seen on most 78-83 vehicles has one location to bolt the transmission crossmember on the driver side frame rail, which is in relative close proximity to the drivers door hinge.
