Ya it's mine. I bought the gauge dealy on ebay from a guy parting out his car and it was quite the unfinished project. It was just three holes drilled in some shell of an AC vent facing straight up in the air, it was bright white, and there was no way to use it.
I took it to a fiberglass shop with a stock AC vent for reference and a 2 1/16" gauge and had her fill in/redo the holes so they pointed in the right direction and make the hoods that come out with them.
It's an absolute one off custom deal, but it could be easily recreated by someone with a decent amount of fiberglass skill.
Glad to see people like it.
And oh ya, the black fuzzy dice will never die. They were there when I bought the car, and aside from the ebrake handle it's the only thing left that hasn't been changed.
