New rallye dash replacement gauges/tachs (some insider news from the supplier)

There is a fitment issue causing light not to shine correctly around gauges? They aren't shaped correctly or don't mount correctly?
TBD. All we know for sure is that there is a definite fitment (design) issue with the ammeter that consistently causes it to contact the center post of the housing when it should not. The fitment issues with the other three appear to be intermittent (these are all individually hand-built, btw).

As for whether these issues are related to the light delivery being off is undetermined. What I can say is that the set that I installed in the Barracuda a few years ago has the same problem. It is not terrible by any means, but also is not right when compared to factory.
