Hello, jeepcamp from North central Wv. Who can help me find rear axle inner oil seals. Here is what I think I know. 1952 F6. The number on the old seal is National 5751. I measured it and came up with 4.553od 3.173id and 1.151thick . I believe the axle to be a Eaton 1350 two speed. I would like Nos, but any that will work will be great. Thanks
