Detailed Description

This Mahle engine conversion gasket set is intended for sealing-related engine service on Ford Mustang, Ford Crown Victoria, Lincoln Town Car, Mercury Grand Marquis, Lincoln Continental, Lincoln Mark VIII, Ford Thunderbird, and Mercury Cougar applications. The kit includes the oil pan gasket and rear main seal, both using rubber material for sealing performance, while omitting the cylinder head gasket and several other service gaskets that are covered by the matching head set.
