Sure, My shelf only moves through 90deg but only because it gets stopped by the cupboard panel above, if that wasn't there then I guess theoretically it'd go through about 270deg until the hinge bottomed out on it's self again but I don't think mine were called 270 degree anyway!
I know how hard it was finding them, I knew exactly what I needed and after much downloading of images and contorting myself trying to imagine how they folded up I ended up with those. The pictures look right to me, as long as you get the ones with the 2 screw holes and not the double glass ones I think you'll be OK.
Rob, Yeoblade, If you want to take a much closer look at their workings just to make sure they're going to work for you then let me know and you can check them out via a what's app video jobbie. No probs.
ANYWAY... Great looking van, sorry for hijacking your post Bill!
