Stock gauges Vs. After market gauges

After I saw fstfish66's dash I decided to do the same thing to the 66 Barracuda dash going in my 65 Dart wagon. I am using VDO gauges as the style I'm using is similar to the face of the OEMs (black background, white markings and red pointer. The VDO's (and most likely all aftermarket gauges) use a 12 volt source, which should be much more accurate than using the 12 to 5 volt limiter. I am in the process of constructing a harness for power, sending unit feed and lighting all the gauges and connecting it to the stock dash harness where needed. No pictures (yet) as my instrument bezel is out to VAE (on this forum) for chroming and detailing.
