how did this come from the factory

GEO, where can you find a new thermostatic sensor that looks like that? I have it on my 1970 Air cleaner as well.

How would you go about restoring this sensor and its respective snorkel motor? I know its very hard to find this exact style. The 1970 heated air intake was the first year, and the factory service manual is awesome at explaining how to service it.

Sorry to kinda steal the thread. Thanks!

Yes, a wing-nut and a washer would do you just fine for the air cleaner.
