I have one that I paid $150 for last year (which I THINK was a good deal even then). I'd sell it to you for the same price. It's out of a 1986 911, 160 mph speedo that is electronic. I can tell the trim ring was removed and the needle was repainted, but it's in good shape and it works.

Don't feel obligated in any way, just throwing it out there...
