Hello guys and gals. I bought a 1999 Cobra (for gas mileage purposes of course!) recently. My left rear axle shaft boot was torn. Unforntunately, these parts are rare aftermarket and not produced by Ford any longer. Their fix is to swap out the carrier and axles out of an 03-05 to the tune of 900 bucks. I spoke with Robin at Mid Atlantic and she told me about these guys. I pulled the shaft and they fixed it while I waited for 60 bucks. They are in Baltimore and their number is 410 752 3000. I highly recommend them.
