Hello Gregg,
Welcome to this forum, seems you have inherited a great truck.
Manuals are available, both original and copies - but we first need to establish the exact type first. Show us a pic of it so we can properly identify!
Sources for parts or knowledge are on here - post your question on this forum and I'm sure you will get an answer or at least a hint in the right direction.
- Hanno
