Thanks for the info guys. I've been doing a full on study for information. I will get back under it to check on some other items.
It is 25,000 GVW. Bed is fully functional & short of a good pressure washing underneath, it is very nice.
It is coincidental that when I was a child, this truck delivered my fathers Farmall tractor in '74. 10 years ago the trucks owner passed away & my father bought it from the family because it was so nice & unique. It had not moved since. Last fall my father passed away due to cancer and it was then transferred to my name. I recently decided to make it drivable. 3wks ago, after a carb rebuild, some new fuel & a battery it started right up. I'll try to post some pics shortly. Thanks again for the help.
