Thank y'all for the replies. The manufacturer will only sell the whole door unit for over $1,000 shipped. Residential doors are taller than these. It might fit, but I wasn't willing to chance being able to trim 2" off the header. Turns out, a local glazier custome ordere the pane and replaced it with one of the same tint as the other panel, for $600. Happy trails y'all.
