Stock Replacement Oil Pans These oil pans are stock replacements for generic factory oil pans and are perfect for restoration projects. They're also perfect for engines that are not intended for racing and just need a new stock style pan, that in many cases are not longer available from the dealer. They feature excellent fit and flat unwrapped pan rails, unlike most imported chrome stock replacement pans that don't even come close to fitting. Also featured are very effective internal horizontal baffles for proper oil control and Milodon's distinctive gold irridated finish.
