Do you have a picture of the dash with the Race Technologies dash in Hellfire? Do you have dimensions of that dash? What all components are you running?
I'm looking at gauge options for my car and had previously been looking at the racepak setup but like this as an alternative possibly. I'm using the Holley EFI which makes the racepak simple, but need to research more details on this prior to a commitment.
Removing the downbars from the front of dash (bolted) to the AM subframe (welded) proved to be a little difficult as the sawsall blades dulled quickly. The solution was the "wheel of death". The 7" diameter carbide disc on a 4"grinder is probably not OSHA approved, but it allowed for easy access to the work area and made quick work of the chrome moly tubing.
