Does the TKO have the same internal speedo gear as the T-5? I pulled my speedo gear out and it was chewed all to hell. So i figured i need a new one anyway i might make sure i get the right one..
The ONLY place I have found that even sells TKO drive gears is Hanlon Motorsports. And as luck would have it, they have a speedometer calibrator on their site, simple input your gear ration and tire size and you're all set. The call Linda tomorrow and she can hook you up. You will more than likely need to swap to a 6 tooth inner gear if I had to guess, I know I did with my 4.10's and TKO. I think i run a 6 tooth drive gear and a 20 tooth outer gear.
