Thought so. Guy over at CTS said they were made in the factory. I don't think they did that until the mid 60's.

They were made at the factory in 56 for GMC and 57 for chevy.

Quote:

Apparently NAPCO reached an agreement with both GMC and Chevrolet to supply them with the Powr-Pak conversion kits, and GMC began to produce 4x4 trucks on the factory assembly line (using NAPCO components) starting in 1956, with Chevrolet following suite in 1957.

There Are Both Line Built And "after Market" In Those Years. You Could Add A Unit On Later. I Think They Bragged About Only Four Bolt Holes To Drill. The Rivet Deal Is A Good Indicator, As Already Said. Another Good Way Is That The Gvw Is About 600lbs More On Line Built. I.e. If You Have One And It Says 5000 Lbs On The Door Plate It's Not Line Built. If It Says 5600 Lbs It's Line Built (basic Number Will Vary Depending On Chassis Type)
