360 Kevko oil pan...what gasket?

What gasket are y'all having success with, using a Kevko oil pan on a 360? The end rubber pieces all fit like crap from what I've tried.

HELP!

Thanks!
I have the Kevko LA pan and used Mahle/Victor # OS30520Z cork with metal carrier pan gaskets with rubber end gaskets. Fits and seals perfectly. $15.56 at RockAuto.
