74 starter override relay

Hey guys
need a little help. I need the correct name of the relay and the passenger side of the engine Compartment. The chev shop book calls it a starter over ride relay. I am looking to replace and cant find the correct name for the chey dealer tp look up...even took the part in! Still no name. The relay has a small rubber button that you reset if the starter wont turn. Also can you tell me if a 74 cam with a full size or donut spare!

I think there is an article on www.corvettefaq.com about rebuilding one. If not, you could try a good auto parts store or big truck dealership. You need a pretty large capacity relay for this.

The spare should be full size.
