I just got my F31s for my 2003 ranger and I was wondering if some of the experts that done this before would give me a few tips. Like what size and kind of nuts and bolts I need to replace the factory rivets when I flip the rear shackle and what side of the leafs is the front (I never ask anybody becasue I thought it didn't matter but I noticed a difference on both ends). My rear-end is factory right now and I plan to get some bilstein 5100s real soon too. Thanks
