maintain- i have one available to me and its heavier duty than stock so i figured why not.
i basically started this to figure out if the drw and srw rears are interchangeable and its not without screwing with overall tire width. massachusetts laws suck when it comes to big tires sticking out even if you have fender flares. i avoid cops as much as possible so i'll be sticking with the stock axles.
thanks to everyone who tried to help me through this issue. i appreciate it.
