47-55.1 Frame dimension measurements

1950 Chevy 3100

I am not in the same location as my truck right now, but trying to plan for a cab buck/dolly. I'd like to cut all my wood at my house and then transport and assemble on site.
Can anyone tell me the following:

• width (outside to outside) of the stock frame at the front cab mounting points
• width (outside to outside) of the stock frame at the rear cab mounting points
• length between the front and rear cab mounting points

Alternatively, if there are cab dolly plans specific to an AD, I'd love to see them (everything I could find was earlier, later or didn't have measurements).

Thanks in advance
