so i just bought my self a "Back Rack" and it looks BadA$$ =)

the only thing that bugs me about it is the bolts are not covered (where the rack attaches to sides of the bed)

I have looked ALL over, gone to the home improvement stores, auto stores you name it ive been. I was looking for large "vacuum caps" but nobody sells them any larger then 1/2 in.

the nut is about 5/8 in. and the bolt sticks up about an 1.25 in. Any help/ideas in covering these would be greatly appreciated! they are an ugly goldish looking things that take away from the look of the back rack IMO
