do you know where i can get a window channel for the front driver's side door of a four door 48 plymouth p-15 special deluxe? mine is rusted beyond repair and i've been watching on ebay but haven't found one. I have a parts listing catalog that says desotos, chryslers, dodges and plymouths all use the same parts in their 4 door cars so they're interchangeable if i can find one of them. I might have to have one made. I learned that the clip has a groove it goes into and then pushes on in the groove to set the locking clasp over the regulator. It's hard when in the door because you can't see it, not as easy as when its not in the door. I practiced putting it on before trying in the door, i got it in.
