Has anyone seen an axle seal like this? I've spent no less than 20 hours looking and have not come up with a part. I'm thinking that a replacement seal was used; one that comes up is a CR 25135 and I can't find that seal either. This is a 2 speed rear end application. Any help from the fellow big bolts is appreciated. A GM part number would be a helpful lead. The link to a picture. Thank you
