Me and Phx99cobra have agreed to switch rear ends, My SRA for his IRS. We will be doing it this weekend and hopefully it will only be a 1 day thing but thats if everything goes right. I will be taking pictures and posting up when all is said and done.
Oh, and if there are any generous shops out there that would be willing to lend us a lift that would be much appreciated!
I am going IRS because ever since riding in an 03 cobra I cant help but love the way they handle. Since I wont be doign any major drag racing with my car I figured I might as well have it handle good for a DD. Updates to come.

A tranny jack really helps. It is not that bad of a swap.

The GT and Cobra Calipers are the same. Just the Rotors and brake brackets are different. IRS cables worked fine when I went to the solid. Originally Posted by 93mustank

Here are some that you need to know. Keep your calipers and pads on each car, do not swap. Take off the exhaust hangers on the gt along with the catback (this includes the 4 retainer clips that the screws sink into. Take off the pinion snubber on the gt. Remove the pinion flange on the cobra and swap it onto the gt (vis versa). The ebrake, obviously have it off, pull the e clips off, pull the head with a set if channel locks or visgrips, if your strong enough, get another set of channel locks and take off the tension on the spring and slide the cable out. It's tricky, I did it by myself, but I'm sure another set of hands would have made it quicker for me. Rent a 3 jaw puller and a brake caliper kit (the rear piston is a screw in, not a press it) from auto zone. The puller will make life easier getting the pinion flanges off. good luck, Gene

You have to switch pinion flanges?
Can you just swap drive shaft?

Does the 99 cobra have the same tranny yoke as his GT? Originally Posted by 93mustank
