Thanks for your help guys. I got the OK from the boss to get the 82 cab. I am assuming what dash parts that are usable in the 78 cab, instrument panel, heater /air controls, etc. will work in the 82?. The 82 looks to have been setup for AC. Not sure if I want to go with AC in the truck. Not a big fan of it and it being a 82 I am pretty sure I will be dealing with the coolant issue of flushing out the out dated coolant and fill it with the new approved one.
