    I may be wrong but that probably won't stop me from arguing about it.

    Your attachment is bolted on. No biggie but not necessary. I'd loop the strap over the short lateral tube at the X and use a belt adjuster to affix it. There's no need for the bolt-on attach except possibly to attach a retracting reel, and given zero experience with those I'll defer on that.

    Your installation method of attachment is not a problem. Route the harness as suggested between the x and the short tube and get rid of the string.

    MY BIGGEST WORRY, however is the material type and thickness of the clamp used to hold the anchor to the rear carry-tru tube. (It LOOKS very Thin!) If it is aluminum it will do you no good in an accident as it will likely tear out especially with two bolts per side. If it is steel, it also has this potential because of it's thickness but will tear out at a higher load.

    My point is, I would make the clamps with thicker material and make them from steel.

    I figured as much. The plane isnít flying and Iíll re-route the belts. More curious about the attach setup.
    HAVE FUN. DON'T DIE.

    Since you're curious? Read chapter 9. And remember, the only opinion you should care about is that of the IA who'll sign off the plane for airworthiness. Not all IAs interpret everything the same way.

    just attach/wrap it to that short tube at center of X brace, that's what that tube is for... no need for mounting bracket
