Hudson and Blue Crown Spark Plugs

Nevada Hudson

Blue Crown sponsored Hudson Hornet racing. Does anyone know what Blue Crown plug the Hornet used? I have a NOS box of Blue Crown 87-SX spark plugs, and wondering what they fit.

According to the Blue Crown books the plug number that was used in the Hornets was an M7L or M7Lx, this number was the cross for Champion H-10 through H-11. The X was a designation for dual ground contacts for the plug.
I do know what Blue Crown 87 fits, but not 87-SX. Are they 18MM or 14MM plugs?

I remember putting Blue Crown plugs in Air Force Vehicles (mostly Fords) in the early 60's. The goverment must have had asizable contract with them.

I have some reconditioned Hudson script champion H8 and J9 plugs that I will sell @ 15.00 each plus shipping. Nice display item.
