Ford F-350 Gas Caps

Hello, I had to have one, I have gas thieves, the issue I read on other sites about this was it did not fit flush, putting it on my expedition, was a job, not because of this unit per say, but when I put it up to fit, with the little aluminum bracket it caused the gas cover to stick out, upon further inspection, it is possible my truck had bodywork, because, the bracket did not fit exactly, first off I had to re-drill the mounting holes for it. Then when I got the screws to align, the thing still stuck out, so I put the bracket on the grinder and removed some material off the corners where it sits in the gas bay, after that, it fit well, the other poor thing about this is those two mounting screws on the door side, they seem very weak and they are very hard to get at to tighten them down, I read one review that said they lost one or more of the screws, they are not solid, so I put crazy glue on the nuts after I tightened it as far as I could, I hope that holds them.. other than that it works, oh and the way the lock closes on the unit itself is semi-loose, I am going to put pads on the inside so that when it closes it does not move.
