WhoooHoo, sorry calmed down now...........
The first picture is definitely something I have been looking for, once found though it tends to cost half of everything you own.
Right, I have the hinges that attach to the door, the spacers look easy to fabricate, but the piece in the roof is what I am after. I presume the brackets are on a piece of metal bonded into the roof section. Its location and dimensions look like its going to be a real pain to replicate.
I could go down the 3B route with the doors, but feel it may be worth the effort to try and get them like the original.
