I have what I think is a 3520/14. I don’t know, Ken, I send you stuff and you just burn it up.
Those Vortex Generators were so hot that the Fire Marshall thought they started it!
If you have one, you have to let me pay you something for it. No rush, I am collecting the parts for a fall project when "this" gets cleared and rebuilt FYI, they survived the fire but were buried when the roof fell in on them in my office.
