You could ask local junkyards what they would charge. Otherwise, what are you willing to pay?
I recently bought a dash (not quite perfect) for my '93 off Craigslist. I got the whole dash, trim pieces, ash tray, glove box, etc. Plus, I got the sunvisors, A/C compressor and coolant/washer fluid reservoir. I paid $160 for all that and the guy helped me pull it all out. I felt like it was a decent deal.
