Part of your air injection system for the catalytic converter. Same as used some of the later 70s -82 Corvettes and some Chevy vehicles! Valve, air injection reactor check valve, to keep air from blowing back from the manifold! here is a listing in one of my corvette parts suppliers! https://corvetteparts.com/item/valve-air-injection-reactor-check-replacement-1968-1982

Tires over 5-6 years old should not be considered safe. The rubber ages and it is slower to deteriorate if inside, but even then 6-7 years is about max to be safe! Remember we drive much faster and more than they did in the 60s and 70s. Be safe switch out every 5 years I& you can!

My 74 has Chrysler keys and door locks and a gm Ignition lock. The ignition key I’d was inside the door panel ?
