I ask because i just put 3.73's in my 95 GT 5speed and iam looking to get a SpeedCal so my speedo and milege will be right on the money!Anyway i can't remember if it's a 16 tooth drive or 18.thanks
If no one replies by tomorrow, I'll let you know. I'm putting in a 23 tooth speedo gear in my car tomorrow and I'll count the teeth on my stock one if someone hasnt come up with an answer by then.
I'm resurrecting this thread to say...I have a 16 tooth gear in my stock 88 with the 2.73 rear end. I also have a 90 (lucky me) that was converted from AOD to 5 spd. I have heard that in 90 the drive gear was changed to 8 tooth. Needless to say, the speedo is off. I think the 90 has stock 2.73 gears matched with the old auto? How many teeth do I need on the 90 gear?
