Summary: I thought these sparkplugs would be difficult to find. They fit a 1936 Ford flathead V8. I was surprised to find that Speedway Motors had them in stock. The fact that the connector on the top of the sparkplugs are removeable made the installation a breeze. The sparkplug wires are held in place using knurl nuts and they fit the threading perfectly.

Yes, I recommend this product.
