oil pan gasket problems la 360

I ordered one of the Milodon one piece gaskets from summit a few yrs. back that was supposed to be for an LA and it wasn't. It was for a Magnum and the pans are slightly different at the front. You can use a Magnum gasket on a LA pan if you want to silicone the snot out of the front corners to fill in the voids but that's the only way you won't have a major leak
