Does anyone out there make replacement wing window assemblies?

Haven't seen any reproductions. There are a pair of NOS assemblies up for auction on eBay right now. Likely to be expensive though.

You see them on e-bay sometimes. I just bought a left and right for my 71 and they look to be in very good shape.. But The proof is in the unpacking.

Only paid 8.00 each though.
