rear end swap ?
 

Will a 87-93 rear end fit in a 97 cobra?

dont the cobra's have IRS?
it would physically bolt in with the right mounts, but you'll need to use the later axles.. they're about 1/2in longer..
I have an 8.8 in my 84 from a 96 cobra with no probs..

Yes, it will fit. You will just have to swap your brakes over to the new rearend.
