Not a very good photo but my old panel is just flat, no curved piece at the top. And I don't see an pre-drilled holes for the rivets.
Lorsar, thanks for the Bud's photos but those thin strips are a little different than the curved part I'm lacking. Dirkbalter nailed it and his photo is very clear. Actually, if you look at the furthest right Bud's photo, it actually shows the curvature at the top of door.
Only question now is where to get the curved aluminum parts (hopefully from a US seller).
Dirk - where did you buy the door cards from?
