Let's just say allot of the stuff here from various vendors come from 4-5 suppliers across the pacific ocean. They have no real idea what goes where on one of our trucks, everything is left up to miss-interpretation miss-understanding of the english language but it's cheap. I would just go out and buy a parts cab or whole truck and you would have all the OEM parts you will need and they will fit. Hopefully the parts that you need are still good on the parts cab. Go to this link it will answer allot more questions than I can.Vernski
