Well, you were close but not exactly the part I was looking for. All thoughs numbers can get confusing! But your post helped me find an old thread that had the answer. wedges for the tip up canopy. Thanks for the help!
It can be used to fabricate the little spacer wedge C723 below the canopy strut anchors on each side... I actually made mine from other stock and ended up sending these back with my small pile of returns after the build. I never found any other use for them.
That's what I finally discovered. Made the wedges last year out of other aluminum, found it hard to believe this big of piece is required for the wedge, but now I have something for my next project. Thanks again
