Re: T5 7 and 9 tooth speedometer gears
I need to know your full tire size not just the rim diameter. Like 245/50/16?

Re: T5 7 and 9 tooth speedometer gears
Can you come up with a set of drive and driven gears for a T5 with 3.27 rear gears and 275/40-17 tires?

Re: T5 7 and 9 tooth speedometer gears
You need a 7 tooth drive and 18 tooth driven gears.
I will pm you with my PayPal and get your shipping info from you.

Re: T5 7 and 9 tooth speedometer gears
I have a 90 Camaro rs that had a V6, when I bought it it had nothing, no wiring no computer, I installed a v8 with all msd components plus a 5 speed, it was originally an automatic, what all do I need to get my speedo to work, I believe it to have 342 rear gears. tires right now are 205 60 15, will be changing to 235 60 15. Thanks for any help you may give

Re: T5 7 and 9 tooth speedometer gears
I have a 91 that I am putting a T5 in rite now. What gears do I need? I am running 275/40/18's with a 3.73 rear end. I also need to know if the VSS off the 700r4 will work or do I need a new one.

Re: T5 7 and 9 tooth speedometer gears
Do you still have these in stock? I am pretty sure I need a 7/22 tooth combination for a 4.10 gear with 245/45/17 tires. Thanks.
