Some good news and some not so great news here.
I found what I believed to be a completely unmolested door. Turns out someone gave it a quick code of gloss black. It's still does look nice all things considering and the picture doesn't do it much justice. If you want something nicer I definitely do have more doors however they have all been stripped and refinished. the finish was done with truck bed liner. While they do look nice and clean, they look nothing like the original finish.
Secondly, I thought I had some original, untouched mech holder hardware but after looking around I realized they are not complete. I do have some nicely cleaned up parts here that were cleaned, stripped and sprayed with a matte nickel finish.
I did find some plastic upper reject bezels but in the process of looking I found a complete set of metal reject bezels which are period correct for early titles such as pole position. They have been stripped and do need a coat of gloss black paint. You can have either set.
Last but not least I did find one more game board style large USPS flat rate box. After doing some searching I found that they no longer distribute these boxes but they will honor them as legitimate flat rate boxes if you use the last remaining boxes. This will save you on shipping considering these weigh quite a bit.
Tldr; this or whatever you want for the cost of shipping
