"Old car Smell" Help

Hey guys, so I've been restoring my 1970 dart, pretty much everything in the car is new down to the carpet headliner and door panels. But after installing a set of Vintage seats in the car it now has that dreaded musty "old car smell" also known as "The Army Navy Store Smell" Any idea how i can get rid of this smell without having to have the seats completely reupholstered? they are in 100% undamaged condition and other than the smell they're as good as new.
