i am doing a solid axle swap on my 03 cobra, and would like to sell my IRS. i will be selling it missing a few things that i used in my solid rear end. it will not include gears and the differential, and brake rotors. you would need the gear of your choice and a 31 spline carrier. it has poly bushings all the way around, diff brace, poly diff bushings, 14mm bolt upgrade, low pro-file rear bolts. i also have a Bassani cat back 2 1/2 inch, stainless steel to go with it. somebody make me an offer on it all. pm me thanks-Jim
