Ok here you go a picture of cans.
So which one is relided? From Left to Right
C)Gargoyle Transition Can
The answer is C.
The Outboard can is the same height as the Transition can.
The oldest one, The Gargoyle Process, is a tiny bit taller but nothing noticeable on the shelf.
The bottom was replace on the Transition can and the dents removed by DB.
So there you go, proof that the relided cans are not always shorter. Unless someone cut the top or bottom completely off it should not be shorter.
