Bro,
I did have a mutha, but it was my own doing. I used a Lincoln rear and that was most of it. The axles were too long and I did not like the tire rubbing. I went back to a stock lenght axle and then had to modify the caliper mounting brackets. I used the brake lines from the Lincoln rear and did not change the master cylinder yet. I am going to do that, as the brakes are a little soft.
However, with your setup, I can't see you needing that. The 93 Cobra did not come with a different master cylinder that I am aware of. I doubt the brake lines will be an exact match, but I am sure you can work something out there? I would look at replace those rotors, as they are cheap these days. I picked up new ones for the conversion for $22 each. It also looks like those axles have the anti-lock gear pressed on them? Those might need to come off, but it is all off an 8.8 with the same body width. I would think you are going to be much better off than the path that I took!
Post up on the progress....
