swap is not difficult at all. actually installing my slp line lock (which i am doing now also) was 10x worse than this. the irs comes out in 4 bolts basically, then just bolt up the new exhaust, contol arms, solid axle, etc. (shortened version). the worst part is gathering all the stupid parts (pinion snubber, pinion flange, ebrake brackets, upper control arm bushings (axle side), etc. all the misc. items). i am using the GT brakes that came with it so i can use 15" rims with no grinding or fitment issues. but they do make brackets to bolt up mach1/cobra rear brakes.
