Oil Pan Gasket Question

Hey FABO,

I need to order an oil pan gasket for a 318 with a truck style pan.

Fel-Pro has 2 part numbers, both with the exact same description.

Does anyone know what the difference is between these two sets? Obviously, it appears one has a smaller rubber end piece. But, why?

I called Fel-Pro... their answer was "one has a thin end rubber and one has a thick end rubber".

Here they are...

Fel-Pro OS6566C-2
