plastic strip molding behind doors---69 charger

[Chatt69chgr]

There is a piece of plastic flexible strip molding that fits behind each door and installs on the unibody.  It runs vertically from the rocker panel up to near the top of the quarter window and is used to hide the vertical pinch weld on each side of the car.  I need this in black.  What I have is green.  Any idea who sells this.  I suppose I could try to dye mine but if not too expensive might just be better to buy in the correct color.

Yep.
It's called "windlace trim", you can buy it brand new repro From Mega Parts, Dante's, Jack's, Herb's, etc. Comes in either black or white. I think they were about $20/pair IIRC.
If yours are in good shape you could dye them with SEM black dye.

As stated I would just dye them.

I would buy new. I had dyed for a while and eventually there were signs of wear and tear showing the original color underneath. It is a cheap enough part that gets rubbed more often than assumed. May as well just do it right for just a little more and never deal with it again.

Dye works fine if you have the paint and prep already, if not then save yourself the hassle and probably a few bucks and buy a new set.
