I am turning my standard 66 manual gauge cluster to an "SS" RPO U14 cluster.
It seems to get your hands on an original '66 RPO U14 you have to be very lucky finding one and then willing to spend like $600-$700 for a cluster that needs to be rebuilt.
I bought the http://www.shiftworks.com/gauges-ss.htm
gauges many years ago, but now I see "correct" metal versions can be had from https://www.thepartsplaceinc.com/Pop...D=IN12613V.jpg
I am not sure if I will switch to the metal gauges or not.
The gauges can be bought as repos, but there are many other parts required to do a correct conversion that don't seem to be available, some of these parts have to do with the indicator lenses.
As you can see from this pic: https://i.imgur.com/COZGgRS.jpg
The standard idiot light indicators get replaced with a Bright/Brake combination. Not only that, but the light housing inside the cluster should not be divided like this one https://i.imgur.com/N7arU8c.jpg
I did buy an extra standard gauge cluster off eBay that was very rough on the outside, but the internals were good, I plan to modify the indicator lenses with new text, and on the green plastic light housing, removing the center rib.
I have an extra set of original indicator lenses:
I plan to wipe the extra set of indicator lenses clean of the paper backing, glue and old lettering. However, looking at this pic again:
It looks to me that both of those indicator lenses are red, and not red/orange? And the text is black for both?
Can someone with a real RPO U14 gauge cluster confirm that the Bright/Brake indicator lenses are both red with black text? Maybe even get a nice high res pic with the lights on?
