727 Governor Weight Differences

D55Dave, "In 1980, governor weight diameter increased by .070" to allow common tooling".
Hey, thanks Tom. Where is that quote from? The old weights are 1" in diameter. It is hard to believe that 1.070" would be more "standard". I measured everything else up on the governor housing and everything else is the same. I have put on a pre 1980 housing and it all seems good.
