Here we have a Rochester TBI-220 Chevy/GMC Throttle Body gasket and oring kit for 2.8L/4.3L/5.0L/5.7L engines. This kit fits a wide variety of Chevy and GMC Cars, Trucks, and Vans. This is the kit you will need if replacing either of your fuel injectors as you cannot safely re-use the gaskets or orings after reinstalling them.
