Which speedometer gears for 3.70s, and 275 60 15s.
I wanted to know which speedometer gears I should use, I have a t5 with 3.70s, and i'm going to be running 275 60 15s. Also, should I bother hooking up the stock electronic speedometer. It isn't going to be computer controlled anymore, I just bought the car and it only looks like the reverse wires are there. I'm almost positive it was an auto trans at first. thanks

I just checked what gears I have, I have two 7 tooth blue gears, and a 20 and 21 tooth driven gear. I think it's driven? can someone please help?
