I am the only one who created these known to my knowledge and I was selling these about a year ago on here to a couple of guys like azdave bought one and a few other members. Deal is, you send me your top steering wheel column cover and I make a mold for you out of it to hold one 2-1/16" or 52mm gauge. Price is $65 shipped back to you, but you must cover the shipping to get it to me as well which is about $3-4 USPS Priority mail. Let me know if anyone is interested. I can paint them factory color red or black for extra $18 to cover material costs, if you dont want it painted, it will be shipped to you in grey or white primer.
Here are a couple of pics on my car and another 2gnt members car:
