1979 450 SLC Armrest Repair
 

Can the front center armrest on this vehicle be repaired or must it be replaced?

Recently a repair shop must have leaned on the armrest with excessive force as it now does not stay in the perpendicular position but flops down on to the center console.
Is this something I can fix or must it be replaced?
I am reasonably handy with automotive repairs but am not a licensed mechanic; just a do-it-yourselfer.
Than you in advance
