Will the apex seals from a 1980 12a fit in a 1984 12a? If so what are the wear limits and tolerences. While I'm writing this does anyone know what all the differences between the '80 and '84 12a were?



Thanks

74-85 12A engine use all the same apex seals. tolerance is in your chilton or haynes manual.

thanks a bunch and i'll look in my haynes manual .
