Anybody in the Metro Atlanta area know where I can go to get them done inexpensively? I plan to order the motive gears from Mustangtuning.com. Oh and 2000Silver, I'm not sure if it is this forum or Stan*net.com's forum, but someone posted a chart of the axle codes on the door panel sticker on all mustang. Do a search on gears on both forums and you should come up with it. Just to list a few of the common ones are..
axle code:
A7 ------------------ 3.07

E, 5, 34 ---------------- 3.27

M, 8, ------------------ 2.73

Y, Z, ------------------- 3.08
