CmdrGeo : Nice truck you have.
As a kid, I grew up near the old Chevrolet car&fisher&vette/ truck plant in North St. Louis.
Chevrolet would use those AD & TF COE's as haulers for both new cars and trucks alike. I remember seeing many of those AD COEs parked in the staging lots awaiting loads after final assembly. It is still amazing how much of load those old 235 engines could haul! {I now wonder if they were 110" or 134' wheelbase.}
I once had an AD 52' Chevy COE that we used to take the front tire/wheels off and use wheel dollies just to lower it enough to fit under the garage door header. It was a hassle , but it got it out of the weather to work on.
From the engineering diagrams in the Chevrolet restoration packs, it looks like the conventional cab AD big bolts mostly only came shortened from factory to 137" wheelbase . Is suspect this was primarily because most "trailers" that would be towed needed that extra area space behind the conventional cab to accommodate the front of the trailer. The COE extra sub frame on top of the standard frame sure helped to shorten that wheelbase.
I have been studying the resto-pacs for frame and cab dimensions and plan to take detailed actual frame measurements soon.
