Found that the passenger window dropped down on the J10, so it was time to fix the bracket and another quarterlight. Getting it out was a bit messy as the manual didn't show all the screws. There was one hidden under the rubber. There didn't seem to be a hole for this one in the new aperture, so I'm not sure if it was a hidden puzzler by a previous owner or not. Of course it started raining while I had the thing apart.
