Hi Zippeay,
GMC used the same headlamp housings for the 4 lamp system 5 3/4" round headlights from '58-'72. Chevy used the same lamp housing from '58-'61 as well. So you should be able to use the lamp housings from any of these truck years. I know Classic parts sells them but only as a full 8 piece kit ($85) which includes 4 lamp housings & 4 of the chrome trim rings which hold the lamps in place. (See photo below) Just checking LMCs site, they don't have them available. You might try Bills Truck shop in Ontario Canada to see if he has any used ones kicking around. I got a lot of used parts from him for my GMC restoration. If I come across any I will let you know.
