I have fabricated several parts for my 73 220D (part of trunk floor, fender patch panels, etc) but nothing else for the pagoda. I will however most likely fabricate front portion of front fender since patch panels are not available to my knowledge and replacement fenders are too expensive and require much labor to R&R. The battery tray on ebay is clearly of finer quality as it was stamped with factory die. The original beads are also slightly narrower than mine but I'm limited by the diameter of the dies in my beadroller kit. Although custom dies can be custom fabricated and I did have one made for me for my 220D trunk floor project. For me, it is more the challenge and the enjoyment of fabricating these panels. The battery tray @ $30 on ebay is actually a good deal in my opinion.
