I just got a 1992 lund tyee 1850 that was severely neglected and abused by its previous owner, it has several chunks missing from its glove box and dash. Does anyone have any ideas for repairing this? It looks to be made of a hard foam material.

Call Lund and have them send you a replacement.
Unbolt the original and replace it with the new part.

tried that, lund doesn't have those on hand for a 1992 anymore.

Can you simply replace the dash with a later year dash that is available?

Or fashion a top from marine plywood that fits over your current console and then pad it over with vinyl from a carpet store or furniture store or automotive repair/refurbish center.
