I am going that route as well. I am going to cut out the radio steel dash off a 1991 Suburban and piece it in my 85. I have manual door panels and the wood grain dash insert that are in perfect condition. I am going to seam it under the dash pad where is isn't seen, just going to have to measure twice, OK maybe a dozen time and cut once. While it is out I am going to fill all the unwanted holes that the previous owner put in it for the CB mount, mic and brake controller while it is out of the truck and also put the dual tank switch in the right spot.
