Any parts store will have a Dana 44 rear end cover gasket, just ask for a Jeep Dana 44 gasket (almost all early jeeps used Dana 44 rear ends) You could also ask for an International Scout rear end gasket. Part numbers might be: Dana #18434, Fel Pro #RDS 6629, Spicer #8122409. These are old numbers they might have been superseded. David Franchi
