i found the moser 31 spline axles i want and im getting alittle confused when i went to purchase them? Keep in mind ive never had to go through this stuff before and im not totally sure what to buy. Anyways, i was going to purchase moser 31 spline axles for my 02 and it says "NOTE if you have a 94 up and need ABS add $25.00 to price above" Is there a difference in axles if you want to keep your abs?
