1927 Chrysler 50 Sparkplug Problem need replacement info

I am trying to get this 1927 Chrysler 50 to run and the spark plugs need changed. However I called AC Delco and they do not see anything that will work. THus I am reaching out to this community to try to help. The model of the spark plug from AC is a C77. Does anyone else have a different spark plug that wil work in their chrysler 50 4 cylinder. thanks

i have a 26 s70 and recently replaced the plugs with stock from autopart store. Mine uses Champion c-160. You can also get head adapters that will thread into head with a smaller inter thread for modern plugs. it is important to note to be very careful with the distance of the plug tip.

Great thanks
