Artie,
I went to the rack store today. The large Rhino eyebolts have the large backing plate. Rhino has a longer opening to get them in. They said they do the same thing you did. Put them in with the end off. Once in they slide on the rail. A properly set up platform will have 2-4 eyebolts in each rail so you never move them from rail to rail. They are way more heavy duty than the Yakima or Rhino small eyebolts. Then you can adjust what you need and not have to repack the roof. Same with the shovel and side Maxtrax holder. You install it and never take it off. The small eyebolts and single single mounting backing plates are identical to the Rhino Racks. So when the Yakima platform first came out that’s what they do and still do as they don’t have as many accessories yet. Sorry for misleading you. They do work but are a little bigger pain to use. They did not tell me that, but I actually bought more eyebolts as what they say is true. You really need them on all the rails. My Maxtraxs and awning brackets lock three of the eyebolts from moving down the rail. I just put 4 more on so I have a more usable system.
Yakima single eyebolts with Rhino backing plate next to it are the same but the color. The one I brought is for the Rotopax so the treaded hole is smaller.
