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)...
Here is an update on how things ultimately shook out regarding the aftermarket replacement gauges. After working with the supplier to resolve the fitment issues, and receiving my modified gauge set back from them, I ultimately decided after all to stick with a working set of factory gauges I had...

It looks like it is not a tach, but an original rallye "Performance Indicator" (vacuum gauge).
UPDATE: D'oh, I see now I was looking at the wrong hole.
:rofl: Yeah that dual speedo tach dealio sure is unique.

**UPDATED 06/05/2024** For anyone who has viewed this article previously, you may be happy (or mad, lol) to know that I have chosen to reformat it into a "real" how-to article - what it should have been in the first place. What was posted previously was at-best, information overload, and at...
This is a follow-up to this thread where I was seeking help on how to do this. After basically striking out on finding any info about this anywhere, except for how to identify the bulb (thanks @toolmanmike), I decided to just have at it, sacrificing a spare bulb assembly if need be. This may...
I am hoping to revive this thread because I am stumped on how to replace this bulb. The original answer I got was helpful, in that I was able to identify the replacement bulb and realized the blue diffuser was removable. I ordered the replacement bulb and then got distracted by other things and...
I got around this limitation when I installed my Sniper 1 by using a time delay relay. I built a simple circuit to keep the start signal hot for a brief period of time while transitioning from START to RUN. This worked fine, but was a little weird because I never took the time to "dial in" the...
I installed a Sniper 1 full system (Hyperspark ignition and a Mopar fuel sender with the pump and return built into it) last year on a '72 Duster with a 360 and could not have been happier. I expected nothing more than easier starts and smoother running, but I got way more. Love the...
Update: The used tachometer mentioned in the OP has been sold. However, if you want a new one, see post #26 ^above^. He was quoted only a two week lead time. You'll want to call them to place an order, because their websites are the worst and often they show out-of-stock on things they actually...
Thank you sir. I feel a little stupid because about 30 seconds after I posted this I was looking at the pic and thought, "I bet that cover comes off...". But I already admitted I overthink these things lol.
