I’m using the 1.3. And the only ones in the 1.3 and 1.4 sections are the pre-modular bed ones. The ones that come with the modular bed are significantly higher.
Ok I was worries about that. I can’t find the 1.03 feet either. I’m trying to find a 1.04 bed mount myself to update one of my Minis. I really done like those older beds.
