sorry for the paragraph size..

Is a 164 tooth.

I doubt that you will find any website matching converters to bells for the simple reason that there is NO converter part number standardization between the various makers and rebuilders of converters.

If you have a small V8 bell the 164 tooth plate will not fit.If you have the 164 tooth bell on the small gear then the starter will not engage. Some starters will rub on the gear - usually it is because a manual transmission starter is being used on an auto transmission. They use different starters.

He has a big V8 bell requiring a 164T flexplate. D7 bells were first used in 1977 and the 157T flexplate, at least for C4s, was last used in 1976.
