Oh, btw, I just clicked on your other thread about that frame. Man, that sux, but I was referring to the cowling when I was talking about a bow and not the actual frame, but glad you checked that frame as well. My cowling was bowed into the cab 1/4" and I had to cut out the windshield pad on the cowling and move them out a bit to get the bolt to line up on the driver's side. This won't show as the windshield hinge and hood will hide it from the outside and the dash will hide it from the inside. It still bother's me, so when I get back in there I'm gonna fix it. I'll either push it out and try to fix it that way, or I'll just cut it and weld it back up. Not sure yet though.
The hassle of returning it to get another wasn't worth it to me, so I just burned it in and figured I'd deal with it later. Now, had I need the actual frame, I'd have done the same as you and returned it!!!
