I am looking at a bow and tarp cargo kit for my M35A2c, and it is listed to fit the 2.5 ton according to the listing but it states the tarp is 14' long which is 2' longer than the bed, plus it comes with 7 sets of bows which seems like too many. I am new to these trucks and I don't want to buy the wrong thing, is that the size they are, 14'? Also, is this a picture of the quick release bows I need with my drop side? Seems the main lower piece screws to the truck but the bows have these latches? Well, it isn't letting me upload the picture of the curved bow pieces.
