I have a T-5 #1352-145 which is .072 5th mated to a 3.90 rear end and 225/75R-15 tires. I want to replace the speedometer gear in the t-5 transmission. Does any one know which one I need or how to caculate which one i need?

Second question. How long is the speedometer cable from the speedometer to the tranny do I need?

Thanks guys
