I'm still mucking around with the shoulder harness install. I finally got some dimensions of the various reels made by AMSAFE and I made a wooden mockup of the one that fits the best for my install. The reel from Aero Tuff won't fit for what I have planned. I think with the smaller reel I can tuck it above the tubing and still have plenty of clearance for the back seat passengers...at least that's the plan! I can't wait for this to resolve itself and I can finally move on.
