Yup, that looks right.
However, the '55 Clipper Custom used the same Rochester air cleaner as the '55 Seniors (same style as shown in that eBay listing), but only because all of those cars were spec'd for the same Rochester single-4GC carb. (The Clipper Deluxe and Super got Carter carbs that year.)
1956 is a completely different story, as the only models with single-4GC installed as standard equipment were the Patrician and Four Hundred. (All Clippers and the Exec got Carter carbs that year.)
Actually, there's some difference betwen the dual-inlet Rochester air cleaners between '55 and '56, but I don't wanna get too far off-topic.
Meanwhile, see this post for clarification on the use of the term "bat wing" as it applies to air cleaners of the period:
