i'm sure you are on this already but when doing the hinge pillars it is always a good idea to have some fresh hinges and hang the door first, then x brace the opening once the door fits to your liking. then take the door off and cut stuff out as required. test fit the door periodically to ensure stuff still fits. also, check the front cab mounts that weld to the underside of the floor since you're there anyway. lots of parts go into making the hinge pillar solid so the door fits consistently time after time.
nice find and hey, they all need a good cleanout when we get them, at least ALL mine do. wife would like me to find something, just once, that we could just drive right away. whats the fun in that, i would have to strip it just to make sure it's good, haha.
