Ordered a locking gas cap for a Dodge Ram 3500 Diesel and on there website it had a picture of mandatory setup for this cap to work. Mine was identical to there picture so I ordered it. Doesn't fit. The part that pisses me off the most is after you pay for it they pop up there little bull$#*! message that nothing is returnable along with no refunds… pretty much crooks in my opinion and wouldn't recommend them to anyone. Stay away from them!
