Guys,
Thanks a lot. I did put a 360 one piece gasket on a magnum 360, with an old style truck pan, and it leaked like crazy. I used a magnum pan on it, with the one piece gasket, and it doesn't leak a bit in my Dakota.
So thanks for the clarification on the 340 style pan. I guess I'll just use the old style gasket, and make sure to install it correctly.
Thanks again,
Dan
