A little update...got a new cab(the last one, I promise) and a little something to go with it:
Its a 68 cab. I picked up the whole truck cheap. The real reason I wanted it was for the 67/68 style front clip! Always loved that style. The cab was an added bonus. Its not perfect, but it is better than the other two cabs I had.
I started a separate thread on the floor install
here.
