Projects 53 1/2t chevy frame

Hey guys I have a quick question... I have a 53 1/2t chevy truck and I am working on the frame and learning as I go. I have the Speedway motors frame that is the same build as the original frame. The new frame doesn't have much info on the measurements for the front cab mounts. It does have holes to bolt them in, but they do not line up. Any one on here have measurements I can go off of so I can attach these and get it right the first time?

Thanks

 

I've got copies of the frame dimensions here Photobucket but they may not be readable. That is out of the 47/54 assembly manual that is a pretty well spent 30 bucks.
I've got a bunch of other AD info that I have put on there over the past 17 or so years that may answer other questions

 

My 48 front cab mounts to a bracket that is riveted to the frame. See if they provided any brackets that would move the mount holes on the outside of each frame rail.

 

If you look they have the instructions on the page where the frame is. https://www.speedwaymotors.com/1947...Chassis-Kit-M-II-Rack-Ford-9-Inch,434077.html
