I ordered a kit for Waukesha D155 with a Delco distributor that has the distributor cap bolted on with weird looking phillips head bolts. Looked exactly like the one I have. Any idea what size socket to buy for these ancient spark plugs? Looks like it will have to be very thin walled since there is no space between head and plug.
