can i use a one piece magnum sump gasket with a LA pan?

Yes, installed one from a late model Jeep Grand Cherokee (1998-2000 something magnum V8 360) one piece.Got it from the Mopar Dealership. Installed in a 70 Duster.It was a Magnum crate engine that the owner installed a deep LA pan.Moroso I believe.It must have worked customer never complained of any leaks.That was 4 years ago.
