hello from pa
Welcome to FABO and good for you, buying that Valiant as a father-son project. You will find A TON of great info and good people here. Best Mopar site on the internet.
BTW - One of my greatest memories is as a sixteen year old kid, working with my dad to put a Dodge 325 Hemi in the family station wagon (58 plymouth). He is 91 now, but we still talk fondly about that project.
