Hornet, what Isspro gauges match factory?
The best factory match I found when shopping for mine was the Danin Pricol (Dpricol)Optix series. They are still the best i've seen out there as far as factory match goes. They are good quality gauges also. I am very happy with them. If you want, I could also PM you where I got mine as they are not a sponsor here, but I recommend to a lot of people for their C.S. also.
If you want to support the site, and use a sponsor here....contact Raul@stealthautomotive. He has a good reputation here and he will hook you up with a package deal.
Good Luck
