No but i'm sure my uncle does. He re-builds jeeps and gets alot of stuff off old mustangs guys are fixin up and parting out
Man i'm starting to rack up quite the bill here. locker, spindle lift, new exhaust, and then tires once all the rest is done. Good thing i love to work....(sarcasm)
im pretty sure mustangs had 28 spline axles. so it probably wont work. find a 9.75 in a junkyard with the 3.73 LS rear end you will upgrade gears and have a stronger axle with LS.
