What's the plug number the Autolites for 1 step and 2 step colder?
I think I have the 764 installed now.
There was a thread listing a lot of plugs with the various heat ranges but I can't seem to locate it through search.

Thanks

stock is a autolite 765

One step colder is a 764 or 104 and 2 steps colder is a 103
