Provari extension cap - regular and mini - interchangeable?

[Macroerror]

Can anyone tell me...is the extension cap interchangable between the two?
So I can just buy one for both?

Mostly,one of my extentions won't fit my mini(its over a year old,seen lotsa use),the other will(its newer).

According to Provape, they're the same thing.
