47-55.1 Frame dimension measurements - The 1947 - Present Chevrolet & GMC Truck Message Board Network

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

Maybe this'll help

Thank you - any chance you have a higher resolution version? I can't read the numbers!

It's very hard to make out the numbers from the book..
It doesnt show the actual frame measurements...so this may not help..
But ..these are cab mount hole locations
front mounting hole width is 47 +.031 -.094
Front to back, hole spacing is 36 + - .094
Oddly there is no measurement for rear width
But on the 3600 series it shows 44...but the frame shape is diff on a 3600

I've got copies of the same diagram here but don't know if the numbers are any more readable. As Mongocanfly said, they are hard to read when you have the assembly manual in front of you because those images are photo copies.

maybe i can help. on my '49 3100 at the front mounts, the frame is 33.5" outside to outside. to that add 11" each side for the "outriggers" for a total of 55.5"
on the back mounts the frame is 38" out side to out side. this does not include any dimensions for the mounts. Front to back, center to center is 33.5"
hope this helps.
