I’m working on a VW based fiberglass car and I picked up a couple of aftermarket heads, unknown manufacturer. They use 10mm spark spark plugs, however I don’t know what kind, part number, etc.
Anyone have any suggestions as to what plug I should get?
Mine ran DCPR7E's, but those are 12mm (d) x 19mm thread depth. I dont think Ive seen a plug that was smaller Diam than that. maybe call CB or VeeParts or Airhead parts.
