If you go back and read Hink's post again, he is talking about an adapter for a one piece crank in a two piece block... I am not familair with an adapter for that setup either.
I do however have the above mentioned adapter for my two piece early crank in a one piece late model block, and it works very well
I really expected leaks and problems installing it, but it went in easy and so far has worked really good without a flaw...
