I have a John Deere 5500 and the left door as you sit in the tractor has been torn off. I went to JD and they want $2000 for the door and glass, which seems kind of expensive. I have looked all over for one at a salvage yard, but no luck. If I could just find the frame parts I can find the glass everywhere. Any ideas would be appreciated. Also any suggestions on maybe putting a plexiglass panel??
