The new line of Mopar Derby shifters are cut on a cnc plasma machine for precise fit on each and every shifter. These are designed to be tight so they do not shift unexpectedly. They have a park lock out pin that is easily removed for working on the car and trailering. These shifters are designed so when you move the shifter forward the car goes in reverse. The new design features a 1-piece 3/8" thick steel handle for greater durability. M.O.P. Mopar shifters are for the 727/904 tranny and come with 1 linkage rod.
