Looking to get all the components for my replacement WS frame ready for paint, discovered the gasket in my vent door was cracked and broken. I got a new SOR gasket with the truck so I'm good there. Digging out the old one was a PITA- then I remembered I just bought what was supposed to be a 64 frame complete. Looked it over and it has the two piece vent door that fasten together with studs and nuts. Am I lucky enough that the later model two piece vent will be a direct replacement for my original one piece vent door? Looking for some inoput before I pull the 64 frame apart. Thanks, gary S
