i put an art carr built c4 into my 86' me not paying much attention, put the trans in without counting the speedo drive gear teeth on the output shaft. im curious if anyone might be able to give me a range of the tooth counts that c4's came with, i guess if i have to buy a couple gears to get it right it will be easier than taking the trans out to look in there. the car had an aod in it and it has 3.08 gears in the rear if anyone needs to know that. thanks for any help or advice you can apply.
