1972 C/60 Dimension help

[eodcoduto]

I won this '72 Chevy C60 on Big Iron last week, for $975 and the cab is perfect! Pretty much stole it and I am heading up next weekend to pick it up using my 20+5' gooseneck. Does anyone have the factory dimension drawings for these? I can find the 1977 online but nothing for 67-72 and there isn't anything on the heritage site. Its 189" wheelbase with a 16' grain bed. Plans are to get it running and use it on the farm for hauling anything that needs hauling.
