1959 CHEVROLET APACHE NAPCO PICKUP

From 1956 to 1959 the NAPCO Power-Pak option could be ordered directly from GM (an official RPO 690 was assigned in 1957) and factory installed on trucks with very few modifications to the original chassis. The 1955 4×4 NAPCO GMC or Chevrolet was a $1250.00 to $1550.00 optional add on. The 1957 Chevrolet and GMC 3100 4×4 price was a bargain at $2549.00 compared to the earlier add on kits. In 1960 NAPCO and GM parted ways when GM redesigned the front suspension on their 1960 pickup line so that it wasn't easily compatible with the existing Power-Pak kits.
