74 Headrests/Head restraints

[Reliabilityman]

Has anyone restored a mid 70's Plymouth Fury III or similar and had to do something with your cracked head restraints? Is there an aftermarket part that will work? Of what did you do? Mine are cracked underneath the head restraint, pictures dont show how bad, but I thought these could be recovered but they cannot. They are molded over the foam similarly like a padded dash according to my upholsterer

Thanks
