certain stuff came out out at different times, my 85 k10 pretty much had every emission device imaginable on it

catalytic converter
AIR pump
Evap emissions control
EGR
Heat riser

yours being a k30 with a higher GVW means it was in a different tier for emissions. Does your truck still have the sticker on the core support?
