I do not own a NAPCO anything, but they were made about 10 miles from my home, in Hopkins, MN. I have been in the building since they moved out of it, down the street to a new address. The building will be or already has been removed to make room for a street and some light rail something or other.
Somewhere around here I have some sales literature from about 1957 I think extolling the virtues of the Chevrolet Mountain Goat, 3/4 ton Suburban - Napco conversion.
I believe the axles were manufactured for Chevrolet by Eaton and modified by Napco for the front drive. I believe all the parts are the same, front and rear except for the axle shafts and the steering parts.
People ask me regularly if my '62 K10 is a Napco, it is not, it has an Eaton/Chevrolet rear and a Dana 44 front with a Timken 4 shaft transfer. My transfer case is similar to the pictured Napco with 1 front and two rear outputs but the pto opening on the rear is not used for driving a second axle, it is still available when used with tandems.
One day I will run across the Napco literature and I will post it up, it is a sales package for a dealer and includes original 8x10 photos (not prints but original photographs).
