Looking to trade my 99-04 SRA with 31 spline axles, 31 spline cobra differential, 3.73 gears, stock control arms, gt brakes, SLP exhaust system, cut stock mach rear springs and autozone shocks for a 03/04 Cobra IRS. Prefer something that has bushings at minimum or a girdle.SRA is in my Mach 1 right now and you can hear/listen to it to verify it does not whine or make any noises.
