- 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.

Great scale that needs some improvements to be perfect
Color: White, Color: White
Very accurate scale, looks good in white, timer works nicely and I do like the concept of the ratio conversion. Shown in photos with 0 measurement drift over time, even without the silicone mat.
To make this the best scale in the price range, I would change:
- The auto timer function. Timing currently stops if you pick up the brew to swirl; you must completely restart the process if you do happen to pick it up. I would change that to only stop on user input (pressing a button).
- The ratio conversion. Why offer XX.0 precision if you can only change the ratio in whole amounts? I'd suggest offering 0.1 increments, selectable with +/- buttons instead of cycling through.
- The silicone mat is not well affixed and slides around. Kind of useless as-is and I just keep it off. I would wrap the whole thing around the measurement platform, similar to how the Greater Goods scale does it, to really keep it secure.
It's not perfect, but for the price, it's a 4.5/5 for me. Rounding up to 5 since a 4 is considered "bad" by today's online rating standards.
