Thank you all !
Rusty, I got in touch with the previous owner (before the consignment place, where I bought it) tonight. He sold the truck due to health issues and I will be meeting him next week to get both histories. Fred will be the first driver and he said he'd teach me to drive it !!
The truck is 80% done, plus10% new parts in boxes, so all I have to come up with is a month and a little cash. Doors will be painted tomorrow and cab will follow in the next few weeks.
I believe I have a high speed rear end too, but I've been wrong before. 5.17 30x5 speedo drive gear and hoping a matching rear end.
Thanks, Pat
