Hey guys! I have a question for you guys. I dropped the stock tranny all over the interstate a while back and got an upgraded cobra spec t-5 now. The speedo gear they said for stock gears is what we put in believing I have stock gears. It is about 10 mph slow now. I have the gear I took out of the factory tranny sitting in front of me and it is a black and has 20 teeth on it. I was wondering if anyone could tell me what ring gear ratio that goes with? The transmission has factory gear ratios and tires are the factory size. The gear he sent me I believe is for 3.55 gears which obviously aren't factory. Thanks guys for the help!
