I've worn my fingers down looking online for a source for interior plastic moldings for my 78 Magnum. Everything is still intact, but very brittle. I would like to replace it and do a new headliner. Anybody have a good source for that sort of thing? I'm afraid it will crumble if I mess with it.

On the good side, it's running good now!

 

I remember those magnums- kind of a bigger type muscle car, they were pretty cool looking.
I don't think they were a large production number car- you may want to buy a parts car in hopes of better condition trim pieces or check to see if dodge used the same trim pieces in another model and find a parts car in that model.
how about a picture of the magnum??

good luck.
