Description
Our 1947-1954 Bolt In Transmission Tunnel are laser cut from 18 gauge raw steel then formed and assembled to bolt directly in to the original transmission cover location in your 1947-1954 GMC / Chevy truck. The transmission tunnel is two pieces that comes bolted together with supplied rivet nuts and stainless steel machine screws. Please refer to the third photo for dimensions of the transmission cover and verify that it will work for your application. Cutting of the factory toe boards or LS Fab Toe Boards is required and the upper section will need to be welded to the toe boards.

Very nice product. Fit was good. Minor angle change for my aftermarket toe boards but otherwise bolted directly in. Very pleased with it.
