This pipe was offset to allow the larger diameter of the oilbath filter to clear the firewall on the C11ADF wagons and standard cab '41 model trucks, and the engine cover on 12 Cab CMPs.

Tony,

Thanks for this excellent information plus photos!

So now I need to get a Cab 11 or 12 Ford to go with this filter . . .
