I am looking for a digital dash for my 1989 LeBaron GTC. Anyone know of some aftermarket parts, or know where I might find a stock on that would fit?

Go to JCWhitney.com. It's not one that will really replace the old gauges, but it's flat, about an inch or two thick, and it'll kinda fit right on top of the original gauges, and it's availible with green LEDs (like chrysler's gauge lights). It'll take some work, but the end result will be good.

One other option...

I belive the later model LeBarrons had digital speedometers, so if you can find a parts car, or get a new one from a dealer, it may fit in place.

BTW, do you have the V6 or the Turbo?
