I've purchased a pretty extensively modified '85 Stang. Unfortunately, the (2nd owner since build) does not have the records from what was done to the car. He says it has 2.73's - believable since it tachs about 1500 at 60 MPH. It still has drum brakes and what appears to me to be a pretty big diff. I want to upgrade the brakes and go 5 lug so I need to know exactly what size diff is in my new craft. How can I tell for sure?
Thanks,
Jason (newbie stang owner)
