Didn’t even think about the one piece windshield. This is what I was thinking.
I am looking at a 3 Window 1954 AD truck, ½ ton. Stock with the 235 full pressure engine.

(Only downside on the original 54 that I can think of was the closed torque tube v the open Hotchkiss on the 55 1st.)

If I acquired this 54, could I purchase a 5 Window big-bolt, (they seem to go for a lot less,) and swap out the cabs? Will the 47-53 two piece windshield adapt to the one piece windshield? Were the cabs modified in 54 at the windshield opening? Or is this a slam dunk?

Will the cab dashboard mounts of a 47-53 adapt to a 54-55 1st dashboard? Is the value $$$ of an AD worth more as a 5 Window, or 3 Window? Of the two styles, what creates a larger interest of the prospective buyers?

For me personally, years ago, I had a 55 1st Model D/Series 3100 5 Window Deluxe, and I just can’t seem to shake it out of my desires to have it in my stable. Am I nuts, or ???
