Smittys54, my 53 has a set of earlier doors on the cab. Everything seems to work fine as mentioned in the previous posts. Clearances and hardware works fine too. At one time I questioned about changing the hardware out, but i believe the door handles are reversed in push buttons. (however i think you can change the glass to the previous style.) I noticed you're not too far from Joplin. I have 4 earlier style doors ( two im willing to trade) for yours if you decide to go that path.
