Congrats to Stick People on an epic FTF!

The Uncommon Common Art outdoor art series ran at this location and many others in the valley until 2019. Although the art series has stopped, some of the art remains. This site saw numerous installations over the 12-year run. If you want a trip down memory lane, see this bookmark list of UCA caches. Or this photo gallery on project-GC.
The final cache is hidden at n 45 08.XXX W 064 18.YYY. To get the coordinates, answer these 2 questions:
1: What 2-digit number is on the door? Call this "A". Then XXX = (A x 2) + 1
2. Is the top half of the door bendy? If no (like a regular door in your house), then YYY = 822. If yes, then YYY = 868.
To get the cache, look carefully. Then look again. The cache is completely surrounded by metal and quite unlikely to be muggled. A cache extraction tool is hanging nearby from fishing line (July 2022).
The hint should help. The questions have been edited for clarity since the cache was originally published. Stick People had difficulties because the questions were at that time ambiguous.
