HELP Needed for 63 Plymouth Valiant Signet Convertible Restoration

I have some items that I am currently working on:

I bought a new top for my car, but trying to find the rear metal tacking strip has been pure hell. Everything on the website as far as parts for Early A Body Chryslers is non-existent.

I am also trying to see how to repair or replace two interior panels on each side of the back seat...they appear to be fiberglass and I am including pictures of all the above.
Help is Needed and Appreciated.
Thank You. Jeff Burgess
