You're welcome. Yes, I was able to keep the wiper posts on my install, but it is very close. I too wanted to be able to leave them in place in case I wanted to switch back to the full screen/top combo. I cap them with a pair of rubber caps I found in the garage that fit snugly, that way I can lean the passenger aero screen down on them without worrying about breaking the glass.
I wish I had a picture up close, all I have are glamour shots of the car far away. But I can certainly take a picture or measurement if it will help. Car is currently hiding in the garage.
I'm wondering if your stanchion ends up contacting the wiper studs, if it would be possible to slacken whatever fastens the wiper transmission and rotate/lean the studs forward a bit to clear. It would depend on how close, of course. And I feel like every one of these cars is put together differently, I'm wondering if I just got lucky mine fit without major issue other than needing to slightly enlarge the four bolt holes in the side skin.
