Might want to read what it says here:

"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. By the end of 1957 both GMC and Chevrolet trucks could be ordered from the factory with the NAPCO Powr-Pak conversion. The two offered identical systems other than the availability of a V-8 and an automatic transmission on the GMC trucks. The Chevy could only be ordered with the 235ci six cylinder and a four speed manual (although there was nothing stopping an owner from ordering whatever he or she wanted in a 2 wheel drive truck and then having a NAPCO Powr-Pak "upfitted" by the dealer)."
