welcome to the site! Stop by the welcome forum and tell us a bit about you and your truck! Any big-bolt specific questions are best asked here, but some of the more generic questions (drivetrain, electrical, etc) that are not big-bolt specific might get more views and answers in their specific forum. There is a swap meet section specifically for buying and selling parts, I am not sure if you need 5 posts before you can see that section or not, but that doesn't take long at all!
Your truck sounds like a cool rig! Would love to see some pics of it when you have time!
