Yes, 6 volt coil. Recommended condenser (via online retailers) is same 1954 (6 volt) versus 1960 (12 volt). Now I just need to find out where that distributor came from! I just assumed the 1954 GMC 248, but who knows. Could be from the 1960 engine or some other item purchased at a swap meet (truck pieced together in the 1970s by someone).
