That's a nice truck Chris, and should be a fun project for you getting that back in drivable condition.
I bought one similar to that about 15 years ago. It was also a 131" wb, but had a stake bed rather than dump. Wound up selling it about 5 years ago. Had too many other projects going, and no time to work on that one. I could post some pics if you'd like to see your trucks brother
PS, will post pics when I can go back into my old computer and find them.
