I have a 1990 7up mustang, 20,500 original miles, almost perfect shape, never even seen rain let alone snow. I'd like to change the rear gears to make it more fun to drive (it is an automatic) but am afraid of ruining any value it has. Thoughts?
Now let's not start that ball rolling. Must keep stock wheels on this car.Of course, there's always the 5-lug swap with an SN95 rear.......
