Well I am gonna get some 3.73 and am getting some prices to get it done and rebuild the trac lock. it spins one tire real bad, but I am being told the trac lock was an option on v8 cars, I thought it was standard on all v8s. So how can I tell if its wore out or just not there. I looked at the tag on the cover and it didnt have a T anywhere on it. Any help would be greatly appreciated.
 
Yeah its the 93 LX in my sig. I was pretty sure they were standard since 87 or 86 when the mustangs got the 8.8. I was just startled by two shops wanting to charge me for a new limited slip differential, when I could just get a rebuild kit But on the other hand the car has been wrecked before, is there any way I could tell?
