See the references for 16660, 16610 and 14060. The addition of the extra 1 in front only denotes a new version but the crown tube reference hasn't changed AFAIK.
I believe the tube is the same size, but I can't say for sure. I know for a fact, however, that on the new bigger style cases the crown is definitely bigger so dropping the 1 on case # will result in the corresponding crown being too small.
Can you get the correct new numbers fro the crowns?
