G29 Shift Knob for ATS/ETS

Make sure to purchase R13-402 switches from eBay, specifically 2pcs Black 3Pin 2Position Maintained SPDT Round Toggle Switch TCA, which stay in position and do not return to center. I learned the hard way by buying some that would revert to the middle, so be vigilant when shopping. These switches fit snugly, eliminating the need for glue, but light sanding might be necessary for a secure fit.
