gauges, stock vs aftermarket

[uncre8tv]

Hi - I am a new guy. Searched on this topic and found a lot of "this is what I did" and "how to" stuff but I'm wondering, in terms of usability, if stock gauges are as good/better than aftermarket?

I just got my '76 Terra, and the stock gauges are definitely in need of attention. Temp and Oil stick on Hot/High, Volts bounces like it's a seismometer, fuel swings slowly around without giving much good info (and jitters a bit too), but the speedo seems fairly functional, a little bouncy, and the glass is fogged pretty bad. I'm sure a new voltage regulator would help some of the jitters, but:

My question is... if I were to spend the time to take apart the panel and clean and rebuild the gauges would they still bounce? and would they be accurate? I feel confident I could do an ok job on the rebuild, not concours, but putting my AS EE degree to work. But if they are going to be a bit out of whack anyways, and if they're going to bounce around anyways, then i don't want to put in the work to rebuild them and then just end up throwing in the towel and buying the $450 panel from scoutparts. If they are always going to be a little bouncy I'll just save the time and save up for an aftermarket panel now.

So.. has anyone gone through the guage rebuild, and if so were the results as solid/steady as an aftermarket panel?

thanks,
Keith
