G-Body Frame Extension
JEGS 64718 frame extension is designed to replicate the longer driver-side frame rail of the 1984 and later GM G-Body cars. This allows for the proper installation of 555-640603 transmission crossmember on 1979-1983 G-Bodys.
Includes:
- (4) 7/16 in. -20 Thread x 1 1/4 (.250) in. Under Head Length x 5/8 (.625) in. Hex Bolts
- (4) 7/16 in. -20 Thread x 5/8 (.625) in. Hex Nuts

- 1979-1983 Chevy Malibu
- 1979-1983 Chevy Monte Carlo
- 1979-1983 Oldsmobile Cutlass
- 1979-1983 Pontiac Grand Prix
Note: Some 1983 model G-body vehicles were originally equipped with a 200-4R transmission and will not require this frame extension. Some 1984 G-body vehicles came with the early (pre-1984) frames and will require this frame extension. If you are unsure, 1984 and later models will feature two mounting locations for the transmission crossmember approximately 14 in. behind the front set of mounting holes.
Specifications:
81 Malibu turbo 400 so I need 1 or 2 frame extensions ? Thanks
Is this the frame extension needed for the th400 crossmember to be installed correctly?
