i have located 2 scheel bucket seats, been stored away for a very long time. the seats are beyond repair, due to mother nature and mice etc. the only 2 parts that are ok and can be saved are the headrests. the problem is i don't know how to release them from the frame. the seller and my mechanic have tried to find a release screw, of some kind, no luck..yet. the headrests seem to be part of the seat frame. All advice appreciated
