ANYTHING will work. You could use the dash out of a Corvette, or a Ferrari. But it ain't easy. The "good" G-body dash, like the one out of the old Cutlass, or a Monte, will require a major rework of the wiring harness. Since the turbo engines depend on the VSS, you will have to fit that in, somehow. Not sure how the tach will work, since none of the other cars had the same ignition as the turbo Buicks. So, yes, you can do it. And no, it won't be easy. Makes the aftermarket Buick units look a little less expensive, when you start to do all the mods.
