I am looking for interior plastic trim for 1977 Cadillac Cou

I am looking for interior plastic trim for 1977 Cadillac Coupe Deville?
This is the plastic trim that goes around the doors and windows. Not rubber insulation but rather plastic trim work. I need green as my car is Seamist Green with green interior

1977 is a long way back...I could start checking the junk yards and used parts dealers. You may attempt looking on EBay. Or you may look for Cadillac restoration sites. Since the car is so old.you may have to settle for another color and repaint them with interior dye. Other years can be interchangeable also. Get the right parts that fit..color may be changed. Is this the textured plastic that slips on the door openings to trim from the interior to the door jamb?? Maybe these guys may help you out:

A big supplier of vintage caddy parts.
The other classic caddy supplier I know is Mcvey's.
If neither, you have to get a hemmings motor news.
Big monthly catalog for classic cars.

This is a job for "Pick A Part", an auto recycling yard that stocks
dozens of older cadillacs. This job is a cakewalk for any "do it
yourselfer". do not worry about agreeing the color. Just pull the
plastic parts you want off of the wrecker and purchase some spray
paint made for vinyl. Of course, you may be lucky and find parts that are both in good form and the right colors.

Hey,
There are many part merchants online. I bought some parts for my 73 on eBay. I know there are lots of others to chose from. they're usually located in AZ and CA. you'll have to look around for 77 parts.
good luck
