Been a while but I now have the new cab completely stripped. I did find there is a "fender tag" like the old mopars only it was under the carpet in the cab. The new cab was an automatic so there will need to be a floor mod. Also haven't figured out if the firewall is the same between the 2 as the donor was a non AC truck. I also drove the truck for the first time in 3 years. Started up as if parked yesterday. Ran a little rough when trying to move though. Not sure if it's crappy from sitting or that it's really low on fuel. Either way it's now in the garage for winter so it shouldn't get any worse.
