Just to throw out some other viable options if you are not set on "original" appearing replacements. I substituted the broken down carton/cardboard/fiber pieces on my project cars with stainless steel (package self/rear seat divider/glove compartment). A local stainless steel fabricator who makes restaurant kitchen sinks/counters took care of my special needs. Shipping the flimsy new restoration pieces to Mexico from the USA would have been more expensive than fabricating the steel pieces here.
