I just pulled the axle out of the '68. Inner seal type. The one I need to seal is in a '70 Valiant. I am guessing buy the Plate on the end that it is the same setup.
Interesting: I think the seal was installed backwards in the '68. The Solid Face was facing into the axle while I was looking at the Hollow end. Also I measured 0.5" width on the one I pulled from the '68 axle yet a NAPA replacement shows a 0.33 wide. The ID and OD look like they should be OK
