1999 Chevy Silverado Pickup to a GMC Sierra

Another special built. I'm converting a Chevy Silverado to a GMC Sierra. ToDos:
- change grille and stuff to GMC
- turn the chassis into a high roller
- put other wheels on it
- add different mirrors
- add side runnig boards
- add fender extentions
- add such a bumper protection
- add a sun visor with position lights
- add side window visors
- add a hitch
- add rear mudd flaps
- add a hugh antenna 😄
- add a tool box on the bed
--- I think that it's all.
