I have those gauges that I purchased from George Graves. They are still brand new and unused. They come with installation instructions. I think George doesn't make them anymore so I'd like to get back what I paid for them. Not looking to make a profit.
Narrowband (yellow) $80
Voltmeter (red) $75
Shipping is $5 for each or both.
They do look great. I just decided to go with VDO gauges.
Here's a link to George's post with some videos: http://www.s14.net/forums/showthread...ghlight=graves
And pictures of the actual items:
