Ok, for rear early P85D you should be looking for 6006353-07-A (matches 1030608-01-A, frt). Parts list shows the later unit, covering all Model S D's was 6006353-06-C. The manual goes lengths to identify the correct pairings, splitting their production on 4/30/15. Rear air units would probably have part numbers similarly taped to the upper housing, and not strictly on the damper. It looks like Continental went to Bilstein, and the numbers you show would be the ingredients to a whole air spring unit. So, look above the shock for that label.
