I completed drilling the holes and through the horizontal struts and main rails.

Now when I remove it from the roof I can re-assemble it on the ground and it will have the same shape.

I labeled all the pieces before removing. including direction

I took off all the nuts on the rail studs. A lot of them are rusting. I should change them to zinc coated.

I had to loosen the studs, Front left, 2nd Front left. And middle right. because they were tight. I will have to re-loosen them to install the rails again
