Dear: rr454
The TKO 500 and 600 have up to 8 different shifter locations (front, mid, back, back location handles 6 locaitons when you add in 2" offset shifter).
To see a design/drawing of the exact locations go to this web site link and make sure you scroll all the way down to the bottom of the page. It will show you all location and messures.
Here's the link, remember to scroll down to the bottom of the page. Hope it helps you out. TKO's handle up to 600 ft/lb torque.
