Solid Axle swap out of my 04 Cobra. I went back to IRS. Housing is from an 01 Bullitt so it is the correct length for 99-04 cars. 31 spline cobra diff(carbon clutches), 31 spline axles, 3.55 gears, QA1 single adjustable coilovers, Ford Racing rear cover/girdle, TeamZ double adjustable upper and lower control arms, TeamZ lower control arm correction brackets and the tubes have been welded at the housing as well. $1500 and I'm throwing in the magnaflow exhaust, parking brake cables and rear wheel speed sensors for the ABS. I will not ship it but if the buyer arranges shipping I will put it on a pallet so it could be shipped by truck.
