GMC "mass" renaming? With "Pickup" as complement?

• GMC C/K-Series
  - for these 1960+ 29 trucks (although some may be Chevrolet trucks and some other can't be really identified).
Plus:
  - http://www.imcdb.org/vehicle_235050-GMC-Pickup.html (IMHO, should be in the GM C/K-Series page, in fact. Unless someone is 100% sure to see a double headlights set...)
  - http://www.imcdb.org/vehicle_592244-GMC-Pickup.html
  - http://www.imcdb.org/vehicle_482692-GMC-Pickup.html
  - http://www.imcdb.org/vehicle_86471-GMC-Pickup.html

• 1955-59 GMC Blue Chip for:
- 22 trucks
(but certainly not as a Pickup, even as complement, for this one, which should have a "Chassis + cab" category. And not as a ½-ton, as it has at least a 1½-ton payload, if not a 2-ton one )
Plus:
  - http://www.imcdb.org/vehicle_399235-GMC-Pickup.html
  - http://www.imcdb.org/vehicle_240372-GMC-Pickup.html (with a Chevrolet Task-Force medium-duty 2 trucks behind...)
  - http://www.imcdb.org/vehicle_448493-GMC-Pickup.html

• 1947-55 trucks, said to be "New Design" by the Stovebolt crew and Tim Lederman, but the latter belongs to the crew...
GMC Truck History (pdf) from GMHeritageCenter.com just say "restyled Chevrolet 'Advance Design' cabs" (p.20).
So, if we keep it, GMC New Design for:
  - 23 trucks. Except this one, which is more likely a Chevrolet.
Plus:
  - http://www.imcdb.org/vehicle_335076-GMC-Pickup.html
  - http://www.imcdb.org/vehicle_273631-GMC-Pickup.html
  - http://www.imcdb.org/vehicle_456726-GMC-Pickup.html
  - http://www.imcdb.org/vehicle_441632-GMC-Pickup.html
  - http://www.imcdb.org/vehicle_426832-GMC-Pickup.html
  - http://www.imcdb.org/vehicle_90005-GMC-Pickup.html
  - http://www.imcdb.org/vehicle_85226-GMC-Pickup.html
  - http://www.imcdb.org/vehicle_42854-GMC-Pickup.html

Whatever the name choice is, and as for Advance-Design trucks, 1948 models should be set with a 1947 MY.
