I recently picked up a replacement door for my 38. It still had what was left of the upper channel seal that extended almost to where the curve of the window opening starts to straighten out at the vertical sides. The ends have a very even cut as if that piece was separate from the front and rear vertical pieces. I'm wondering if that's the way they were built and all the doors that are missing that upper piece had them originally and have simply fallen out at some point??
