Yours second from right? If it had a housing at one time that is:

Original '34-'37 Ford plugs were Champion 7's, which are 18mm. $2.00 each used working.



Or, screw top on EBay, $9.99

Here's a site with your plugs spec's:

OK that makes more sense. Thanks CoolFrayers

Sure thing AA!
I like your second picture, you can see the rustline from where the housing was. Call me a gearhead.

good ID. The housing part can separate on the Champion plugs. I had one seperate, in the 80's, as I was driving down the expressway. Blew right out. Sounded like a blown head gasket. I was glad to find out that only the plug had seperated. I never will buy Champion again.
