So looked at different cars in the junk yard today got me thinking about a dash change or at least guage change. I know the newer cars are all controlled by bcm and ecms, even the Fiero. So what would be the limitations to switch to something more up to date? Would I have to use the 7730 ( I think) and reprogram or the car I took the guage out of and it's ECM or .... I figure some of the cars would even require the seat module and no telling what else.

Are there companies or people on here that make guage that would fit other than the digital one?

There are many individuals and companies that can supply analog gauges that work in a Fiero. Search is your best friend in this matter but I can supply an example from personal experience since I have VDO gauges in one of my cars and they would work with either a conventional distributor or a 7730. Some minor mods may be necessary depending on the specific engine/instrumentation combination.

The Fiero really has no computer control of any of its instruments.
The speedometer is run off of pulses supplied by the VSS, instead of a cable. The other gauges are fed by senders/sensors as they always have been.
They don't really start being controlled by a BCM until 1996, or thereabout. (The beginning of OBD2.)

The Fiero ECM is fairly primitive, in the grand scheme of things. Really all it controls is the fuel injection and ignition timing. (Of course there are inputs from other sensors, but that's what it all boils down to.)
Later ECMs/PCMs (starting around 1991) also controlled automatic tranny shift points.

Altough not a clear picture I found the ring portion in a vibe. I snatch it and then put it in one of the Fieros for maybe grabbing it later. I googled Aztec thinking it came out that model and on a side not didn't realize this model could look this good.
