the only thing I had to buy was the rear cab mount washers... I think they were like 80$ for the pair. I'm sure if you looked around you could find some big washers and nut's... I have no idea why they sell cab mount replacement kits that have no hardware... pissed me off after spending 80$ for the kit only to have to spend another 80 on the stupid washers. Like I said I would look into finding some big washers and nuts... just get some good ones... not the ones they sell at wall-mart...lol
