I noticed their are a lot of lighting owners on this site. i need to ask a question, after my ford loving friend saw my SRT-10 he went out and got a lighting. since then i installed a billet gas cap door from my local dodge dealer, now he wants one but people are telling him they don't work on the step side bed. has any lighting owners installed one? and if so where did you get it and how much? thanks for any help.
