The 5.625:1 CWP and the 5.25: 1 CWP are exactly the same overall dimensions. The only difference is in the 'thickness' of the teeth so as to get 3 more teeth into the same diameter crown wheel. That was done so that the lower ratio was able to be fitted into the same casing as the 5.25:1 version. That's the Achilles heel of the 5.625 CWP as the 'thinner' teeth lead to the set up being not as strong as the 5.25:1 version and so many of them being destroyed whilst trialing - mine included.
The Ulster 'Big Banjo' casing was larger than its touring counterpart but that's a different discussion.
