You don't say which Genie you are going to use so I don't know how much your spending. Below is the shifter I use now.
You will want to know which way the cable exits from the shifter. Most exit from the front but I want a rear exit, so I bought this B&M shifter. It has a 12.72 inch shift lever length.
It also has a reverse lockout and neutral safety switch.
$260
The B&M Unimatic is one of our easiest shifters to install and operate. Our engineers designed this performance automatic shifter to resemble a manual 4-speed shifter. This shifter uses the factory transmission detents for easy positive shifts and is an ideal replacement for moving your column...
