Love this truck! And enjoy watching your videos in my garage while working on my 85 4x4 720. Literally same things youve accomplished i am working on (only I am dealing with a single cab ST). Keep at it!
I would suggest tossing the manufacturers hardware and substituting with grade 8 bolts, washers, split washers, and teflon nuts. Last longer and less prone to dual metal corrosion. Your local Tractor Supply charges by the pound.
