if there is an identifier number i'd give Newark Electronics they have an 800 number. they are hugh and might be able to cross it. i get all my electronics from them for my CNC equipment. just a suggestion for a solution.

another way to go is to buy from petronics for about 70 bucks and replace all that nonsense. i will do that to save my switch cause i plan on the 72 being all original. but to merely drive it the petronics is a much stronger ignition. here they are http://www.vintageperformance.com/retrorockets/index.htm
