The problem with bolt on is that 06 need to have the u bolts flipped, or do a front mount on the axle. For simplicity, this guy ended up with large gusset weld on which can be purchased for 660 bars, 84 frame mounts + freight to your door
Weld on would be fine. Im just not sure where i would weld them to the axle. Ive looked at it and their isnt a lot of room to work with. You have any pics or anything i can take a look at about them?
