I know I am asking for a lot of info, so bear with me. I have some experience with the 41-46, but little with the AD trucks. I did a search on AD Cabs, and could not find detailed differences between the 47-55 1st except for the mounts. Is there a expert out there?

Has anyone replaced an AD Cab from a 3 window to a 5 window? Are the AD Cabs, doors, windows etc. interchangeable? And with the big bolts? When did they come with vent windows? What about mounting of fuel tanks? Instruments?
I think you can see where I am going.

Any and all assistance appreciated.
