Hi: There are several diferent starter plates for these engines. Ford cars were diferent than Mercury Cars and trucks were diferent than either. What are you using it on, I may be able to help. Stewart sdarr@mts.net
I do have several plates and good starters. You need to tell me which bellhousing you have. Most of the flywheels have the same number of teeth, but count just to be safe. Plate and starter $50 plus shipping from 83401 call 208-524-3995 with questions
