Original rear spoiler (D80) hardware question

[Enoch]

Here is what I believe is an original set of rear spoiler mounting hardware that I pulled out of the bin yesterday that's been sitting for well over 25 years. My question is has anyone seen this style reproduced. The forward nuts have the large captured washer with nibs and an e stamp on the top. While the rear acorn nuts have a machine turn down top that comes to a point.
I've seen several different original manufacturers of rear spoiler Hardware but this one's unique to me and I wanted to make sure it's legit before I list it. Any input would be appreciated. Thanks
