I've got something:
3.6/3.7 speaker stands, made by a local welder who got one arm a bit lopsided but the screw holes are in the right place, I had these made to work with the stock feet.
The arms have pieces of a gun cleaning mat glued to them to keep them from marring the speakers, longer stainless steel screws included.
The bases are filled with oven dried sand.
Too large and heavy to ship so local pick up only.
I found the bass to be too pronounced for my tastes with these stands when used with the 3.7s.
$150/pr, pics to follow, stands located in zip 17363.
