I did the 700r4 to T5 swap and after a big headache I found a speed sensor for it. Through my searching I have found two gears for it and I was wondering witch would be better to use. I have a 3.42 rear end and the two gears I have are 19 tooth and 20 tooth. Witch would make my speedo more accurate?
Thanks,

Depends on your tires, but stock is the 19 tooth. The 20 tooth is for 3.70's with larger than stock tires.

Only if you have 28" tires. For stock 25.5" or 26" tires, the 19 tooth works well for 3.42 or 3.45 gears.
