The 99 Cobra differential is a direct bolt in upgrade, but I don't think the control arms and other stuff are interchangable.
The 03 Cobra stuff won't work cause it is a 31 spline setup.
Thanks for the quick reply. I am talking about the whole self contained unit. Do you think there is any way to bolt up the whole IRS from a Cobra? Remove the complete IRS from the SC and bolt up one from a Cobra. Is it possible?
The Mustangs are a few inches narrower than T-Birds, and the geometry and mounting points are completely different. Don't think there would be any advantage to this.
Try using the 'search' feature, this has been discussed on here previously.
