Very nice, glad it's working out for you. You won't regret having a quadrant. It's very nice, and it's been working perfectly for me. It's every bit as comfortable as the one in the RV-10 and although you found you liked yours 1" lower, I find the position is perfect for myself and my 15 year old daughter both. I verified the positioning with her when we took these photos and she says it's great there.
I did add some side covers for it late in the summer, but just realized I never posted any, so I took some yesterday before our flight. I covered the sides in vinyl and foam backing with a hard back plate, so they are nice and padded and you can rest against it now comfortably. It was simple to do. I also added USB charging jacks on the side, for ipads and such.
I have some additional pics now on my website too, including some of the nice A-700 heater vent control cables. I'm VERY glad I did that. They've been working out excellently this winter!
Also you may notice in the pics I added headset hangers a week ago. They are glued on, so nothing riveted permanently.
Here are some pics of the quadrant covers:
