My trim pieces will be reusable. They are quite pitting, but not all the way through. A thin coat of filler and high build primer and they will be fine.
As far as wood, I bought several pieces from Jim Rodman at Autowood, like the A and B pillars, windshield bottom and top, one sill piece and one door header. I duplicated the other sill and door header on my own. I had enough wood in my cab back to duplicate that. A new roof frame work (bows were kinda tricky) and then made the new roof slats. I have one door done with new wood and just need to do the other side. The seat riser was easy to figure out after I got some measurements off a fellow members truck who lives about an hour from me. Floor boards need to be made yet but are also pretty straight forward I think. I just need to get the engine and trans in with pedals etc so I can figure out where to cut holes and slots. Doesn't your cab have all the wood?
I could lend a hand with measurements if needed.
