I had a look at some sales literature, and the cj5 for the year does look similar in design but perhaps a little different dimension.

There does not have to be a modification or installation instruction when a supply item is changed. Sometimes the new stock could be put under the original nsn if the item does not have a substantive difference, but more often the nsn microfiche will have something along the line of wse (when stock exhausted) use 2530-xx-xxxx-xxxx .
Sometimes there could be a message, other times it could just be an advice notification from supply as to a stock number change. You would then annotate your parts manual or your fast moving parts book.

Edited to add another sales brochure of a CJ5 mirror. Same photo as shown as a later post but thought it might be good to have them all together for comparison
