So, both new door windows are in. The first one took six hours and more than half a dozen attempts. Second guessing the TSRM is, as usual, a bad idea. Follow their damn steps! The second one was complete in well under an hour.
As it turns out, aligning everything so the window goes up far enough to seal, yet doesn't hit or scrape anything isn't trivial.
Now... what to do with two used pieces of glass? So far the top idea is transferring fingerprints from the neighbor I dislike onto it, then tossing it off an overpass during the witching hour.
Mounting the seats isn't going to be as easy as I had hoped, either. Some fab work required for the brackets, and I still haven't learned how to weld. Another item on the bucket list!
