Best guess on my end is that the bars are out of spec and Buck is trying to sort it out. Seems to have been numerous instances of the manufacturer being incompetent so far.
From Buck's photos (yes nearly 3 weeks ago now) I do think they've made it to the HVAC shop. Maybe he's been clever and changed the date in the filename of those photos from an old order but I don't think he's that kind of guy. On one hand I appreciate not getting false-hope posts, but on the other hand another huge gap of time with no communication, despite a lot of people trying.
Personally I'm coming up on 4mo since I paid - PayPal protection isn't indefinite so unfortunately I'm pretty close to starting that process. Not looking good from my view.
