OK, got it done today. Took my time bc I was investigating why the PO had set the first bimini top in a different location... answer, unknown...
followed the instructions and mounted the hardware as intended. It works as it should.
I just need to attach the strap on the sun deck and it`s complete.
but, there is a slight flaw with the directions, when they say parallel, parallel to what, nothing is straight and I`ve pulled more lines and marks to check it. the only really easy mark is the very first hole for the sliding track...
The plastic anchors for the rear support bars was a bit trying, but we got it done. whew...
here`s a few pics.
