I have acquired a dozen BETHLEHEM FIVE POINT SPARKPLUGS. The boxes have no part #s but only say 7/8"-18 S.A.E. Price $1.00.
Do these fit the Model T? I have no use for them but am trying to confirm what they fit. Any info will be appreciated.
Model A would use them.
Model T uses 1/2" pipe thread.
Keith, Keith! For shame, you forgot Yvonne's Fronty uses that size sparkplug.
Here is a link to some images of options available in the day......
Thanks for the feedback.
