Good post, MNSmith.
Those parts from Wheelwright Restorations are beautiful. The price and quality are excellent - there is no way you could find a better price for that quality of work. I wish that those parts (and his other suburban parts) had been around when the metal was being replaced ($$$) on my suburban.
Often, he makes these parts in "production runs" and once they are all sold, it could be a while )or never) before he makes them again. If you will need them for your restoration, think about trying to buy them now.
The suburban rear quarter panels are also listed on ebay. These are the lower cab metal betwwen the side doors and the rear fenders.
This is the same persaon who makes the hand-made panels that are sold by Jim Carter.
