Shifter Tunnels
Shifter Humps
These products are called humps, tunnels or porches. They are used to convert column shift (automatic and manual) floor pans to floor shift. Of course you can always cut a hole into the side of your transmission tunnel and put a large
boot over it, but if you want it to look factory correct, and want to use a correct shifter seal or console you will want one of these.
Most of these parts had no GM part number and weren't available from GM as far as I can tell, so I can only use what the aftermarket manufacturers use as applications. I will use a more common sense approach then other resellers, to determine applications.
