Where can I get a rear diff cover seal?

why do you need one. you can use the black rtv silicone and it works just fine, all the new detroit diesel engines use it without a gasket, no problems. or if it really bugs you, go to the napa store and buy gasket material and make one. the black silicone is a life saver i carry 2 tubes at all time in my '67. mark.
