Does anyone know the actual name of this part, the part number, or if it's even available to buy separately from the door panel? It's the trim piece on the upper part of the door panel that the window runs against.

 

Did you ever find out?

 

No, only thing I have come across is the piece that goes on the outside of the door. I asked Z1 and they thought it was part of the door panel not sold separately.

 

Try going to a dealership. They can print you out a diagram of the door with every part number on it. That's what I have to do sometimes.

 

I'm 90% sure it can be replaced, it has a single metal dowel at one end and bent metal tabs holding it in place. I doubt that it can be purchased separately. I have several door panels but I don't know if shipping something with it's length would be worth it... I'd suggest looking for a salvage Z in your area
