uh yeah, my bad

I went back to pg1 to hit the link and saw the third pic posted again, with the more than obvious pulley. Looking at the engine shot I thought it was an idler, but seeing that makes it obvious and yep, just like the Fords. Good eye. I thought the pulley driven "charger" looked damn small

but I just took that ball and ran with it anyway.
