Which oil pans work?

magnumswap.com covers this. They even claim that you can use the magnum gasket instead of the older ones on the older pans, with some mods.

Personally I am going with the KEVCO since I am spending the money. Dont forget that you gotta pay for another pickup along with the stocker pan. In my case, by the time I figured in the pickup, I figured I could just save up a little more and get the KEVCO. Good bang for your buck.
