Rob, To the best of my knowledge, Lancair never made canopies or window glass in house.
When I was looking for ways to remove masking tape adhesive from my canopy, I talked to Lancair
and they referred me to a local company not far from them that has all the molds for their kits.
I don't recall their name, but they told me they have the molds and can make what you need.
I suggest you call Lancair, get the name and deal direct.
