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.. 

This more extensive kit is for those with say T700 Auto with Overdrive transmissions, rather then the regular T350 or T400 auto.

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.

Comes with fitting instructions, .. requiries a bit of skill but well engineered kit from a good US company.

Fits:

73-81 Camaro

69-81 Firebird TA
