Greetings! I too have a 68 Step side that I am restoring. Feel free to look through my Build Thread at
https://67-72chevytrucks.com/vboard/...d.php?t=815278
Your cab will need a lot of work, but that is what makes it so rewarding. I watched a lot of YouTube videos (PaulkC10 and Gibson63), both of those guys were really helpful.
Best of luck and I am really excited for you and will follow your build.
Cheers-
