Up for sale is the quarter window slide for a 1970-74 E-Body Dodge Challenger or Plymouth Cuda or Barracuda. This particular one came out of a 1970 Plymouth Cuda, but I think all e-bodies are the same. It is in very good condition, and still has the adjusters included.
Be sure and use the "up close" feature to see the exact condition, compare it to yours, and ask questions prior to purchase.
