were can i find a dieplate 7/8-18 ? i guess it is the right threads for the sparkplugs on model A?
you are correct, 7/8-18 is the correct size for the model A plugs. You can purchase taps or dies for this size through tool catalogs such as McMaster Carr. They are at www.mcmaster.com Odd sizes such as this are not cheap!
