Description

This is a brand New heater box seal set for 1963, 1964, & 1965 Buick Riviera models with air conditioning AND without air conditioning. This heater box seal set if for the engine bay side of the firewall for the heater boxes. This set is an all inclusive seal set. Not all of the seals / gaskets in the set will be used (depending on which year and weather or not your car has AC). There is a strip of butyl that will need to be cut to length to seals the “middle” fiberglass housing to the each side where it touches the metal housings. An instruction sheet will be included and I am happy to answer any questions and help with the installation process.

If you need a new heater core please see my other listings or ask.
