I have two HC inner wings, they have been chopped about a bit ( battery tray has been cut out, but its still there, just needs welding in) and the edges are a bit frilly ( only the very return edge at each end). I can't for the life of me remember what the upper return edge is like but as far as I can remember they are good. I also think both hinge panel areas are good, I can send you pictures if you like.
I bought these to repair and to make pattern repair panels from, but have given up on that, so make me an offer
I can weld the batt tray back in for you if you like but the price will have to be including my labour and materials then. up to you
