Brad, the invoice looks to be more dealer specific and is not as detailed as your example.
I do have a scanner and will block out the name and post a copy soon.
I'm going to guess that if Glee had taken delivery of the truck w/the 600/16 tires he could have saved a little $$$. Oddly enough the very old spare, perhaps the original was a 600/16.
Either the salesman was good or Glee figured he needed bigger tires for the bigger produce loads he was going to carry.
It's amazing to think of the mindset of the folks that lived through the depression and 2 world wars. No radio and no heat on a brand spanking new truck but horns to clear livestock out of the way and a bypass oil filter to prolong engine life. No frills.
I'm lucky in that I knew Glee the original owner and I'm still very curious in what he sold to pay off that $600 note. He knew how to trade
