WTB: Aluminum Mandrel/Drive for my vaccum pump
Anyone have a extra/not-in-use aluminum mandrel with the Pontiac 4-bolt pattern? I have a steel one, but darn that thing is HEAVY!!

I found these to be the best. Allow you to retain the balance bolt. There very light.

I second that. I got one and it appeared to be a BBC one with added holes to fit a Pontiac. Maybe you could find a BBC one on ebay and modify it for cheaper. It said something like "aerospace components" engraved on it.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
