I have done it a couple of times. It's not too hard but you need all the parts, not just the dash.
Steering column, signal switch, crash pad, and you have to drill a hole on each side between the windshield and the crash pad to bolt up the corners of the dash.
Older cars had a fitting for a nut there, newer cars would need a captive nut or I use a carridge bolt and you have to look hard to see it in the inside corners of the windshield.
