I bought my 88 GT a few months ago and was told it has 3.73's. I have no way to tell as this is my 1st mustang. I went out today and drove the car documenting some info... let me know what you guys think....
2nd gear at 30mph 2400k rpm
3rd gear 50mph 2800k rpm
4th gear at 50mph 2200k rpm
5th gear at 50mph 1500k rpm
Thanks
