They are not factory moldings so finding a replacement to an aftermarket part is going be difficult since they're one off...
If it were me I would remove them if possible and replace them with aftermarket adhesive ones to look more like the factory since there is really no way to fix the issue with inserts that I am aware of and you have to deal with rivet holes.
My suggestion is a Google search... you might be able to find some sort of vinyl trim that can act as an insert.
The aftermarkets are 5/8" wide vs. the factory 3/4", not sure if you can still find them though... I know aftermarket black was available a few months ago with a texture to it but colors were discontinued a few years ago.
Stuff for these cars is slowly disappearing,
www.rockauto.com is slowly drying up with replacement parts for these cars, I get closeout emails once a month.
Sucks...
One thing I do have is light blue vinyl side molding, it's about 1 1/4" wide but you might be able to fashion it somehow...
