Most of the damage to the Land Rover hardtop is easily repaired but the frame around the driver-side window got buggered boogered up and it was going to be difficult to straighten so I purchased a replacement.
It just slots into the bottom of the door with a couple of bolts. Good as new once I get it painted. I continue to marvel at the simplicity of the Series Land Rovers. I can think of nothing analogous in modern vehicles.
