That cab is all welded together. If you Really, really want to get inside- youcan open it up from the outside. Cut the roof all the way around the rain gutter, and you're in. You'll find, among other things, a small bit of factory sound deadening. If you putting in seat belts, you'll have access from above and below for the shoulder harnesses. If you put new insulation back in, don't put too much in because the roof will stick up too high. While you're in there, check the area over the windshield very thoroughly. Mice lived in his area on my original cab and did enough damage to warrant a new cab. I'm putting screening at the bottoms of the corners to slow them down the next time. K10
