So are the rba sections really NOT interchangable between the STM and the TTM?
I have a bunch of STM RBAs, but the TT I recently bought didn't come with one. I ASSumed they were interchangeable.
As Myk mentioned, All the Versions of the rba Sections are Interchangeable. Just like the Different Air Flow Bases are Interchangeable.
So if you like the Newer Lower Profile Bases, you can swap those for the Bases you have.
