are the extension caps the same for standard & mini?

[Clovery]

I have a mini, and I'm thinking about buying a standard size provari. I never bought an extension cap for my mini. I'm wondering if I buy one extension cap, can I use it on both of my provaris? Or are they different sizes?

They are the same cap from what provari tells me....asked them before.
