Sounds good. (It also occurred to me to try to attach the top clip after installing the linear rod support, however I wasn’t sure if there’d be enough access space to tighten the horizontal bolts of the top clip. Hopefully there is.)
4buck and Richy, I found that post I was referring to where someone (geertdoornbos) ended up using slight shimming to fill the excess space under the linear support rods. Its a good post to read: Maslow 4 assembly guide feedback - #85 by geertdoornbos
Here is a photo from there. The following words from there resonated with me: “A good fit with no material stress and parallel rods.” I think if one has made sure the rods are seated flush and so are the top clips, and the gap underneath still seems too much to try eliminating by over tightening, the idea of filling in the gap with some solid shimming seems like a potentially good solution.
