Value of an A-833 O.D?

I paid 50 bucks for mine and it's iron case and iron tail shaft and looks like new on the inside. THANKS SHELDON!!!! Paul, it'll hold up behind your 451, but you'll need to drive it very carefully. If I were you and wandet an OD I'd just bite off a 518 and be done with it. You'll need an adapter plate, but big whoop.
