Roof side trim

[Wirenut]

Can someone clarify for me the roof side trim application. I have a 63A and need to install my roof side trim, I called Obsolete and they said they do not have a source for those fasteners. They do howler we sell the fasteners for the 64B. I had a 64b and I'm almost certain it was the exact trim. I know the door window trim us different but I do not see any difference in the trims. I'm thinking the fasteners should be the same unless the holes might differ. Any help appreciated.
