This will allow you to have the NSS moved from the base of your steeing column to the factory floor shifter. You will still need to do the wiring but you reuse the original Switch.
For most cars of this build with unaltered AUTOMATIC transmissions.. T350-T400
For those with the badly engineered and troublesome.. NSS that is activated by the linkages on the bottom of the steering column this may be the answer your wanting..
OR for those with and Overdrive trans & RH Drive cars that are needing to simply re-engineer the Reverse and NSS attributed on most all RHD shifter conversions that were done by somebody once.
Requiries a bit of skill but well engineered kit from a good US company.
