Welcome, Chahn1980!
You've come to the right place to get some help!
Just a thought... sounds like your wifey's "go-ahead" is an open door to achieving this dream. Congratulations! I was also fortunate that my sweet wife encouraged me to fulfill mine.
Concerning your find, if the seller can't help you obtain sufficient information to obtain a title I agree with John, you might look elsewhere... This is an opportunity to find your truck. Good luck, buddy! We look forward to hearing good news from you.
