Customizing a rally dash

dartcuda1 is that fuel gauge 2 5/8" or the 2 1/16"? I'm doing the same thing on my '74 Duster but with Autometer carbon fiber gauges. Carbon fiber is kinda my theme for the interior and I'm in the process of collecting the pieces for a modded rally dash. Picked up a damaged bezel from another member this morning and scored a '70 dash frame and wiring harness for free this summer from a friend's friend who was forced by his county to scrap about 7 a-bodies. Damn shame there was a lot of good parts left on those cars but we got there late in the afternoon the day before the wreckers started hauling them off.

Did you use the metal gauge housing and if so any mods needed to clear the spedo or tach?
