New radiator installed and truck out in the sun and daylight as i took it for a spin around the block a few times:

Thanks to the Stovebolt's for all your help and knowledge with the thermostat, radiator and cooling system. FYI: I have already given the old 261 thermostat housing to another member for his use on his truck so I don't have any longer. Sorry but I'm sure he'll put it to good use!
