Because one of the bolts on the differential mount was sheered off, and the other one just kind of dangling. I had the aftermarket diff brace installed a few months after I got the car (didn't want to do that one myself just yet), and the shop that installed it didn't use any kind of locktite whatsoever. I'm not going to name names, but I won't be going back there again. One of many problems this shop has had recently with my friend's cobra.
So while the IRS is out, time for some long overdue upgrades. I need to order some bushings, lowering springs, wheel spacers, a new diff cover and a new diff mount. Can anyone recommend any kits/deals right now?
