I'm in the process of planning this swap myself to complement my T5 conversion and wilwood front discs. I bought an SN95 mustang rear. It's too wide for stock offset wheels but is perfect for the 2002 bullit style 17x9 wheels I'm running. I'm cutting off all the brackets and the "ears" for the upper arms and welding on spring perches. The mustang rear is centered and has 5 lugs, limited slip and disc brakes. I plan to use a 95 cobra master without a booster. Just some food for thought.
