is it difficult? doesnt seem too diff., anyone done it? pics? suggestions? anything, i was going to be using a half top, but i decided that i would just do something else, i think the top wouldve been cool, but it needed alot more work than i had planned, so i decided i would try and make a roof rack....i will be using it to mount a full size spare, and maybe throw a shovel up there, any suggestions?
