You can keep the uppers, but you can't re use the sliders in new skins. They are a complete replacement piece. You may be able to reuse the frame, not sure on that. But the window is sealed into the skin...I quess what i should have said was when replacing door skins can i reuse the existing metal framed slider windows.
have the same problem but i do have some pieces of it from PO. Mine is the spring loaded latching part that's missing, still have the rest of the hardware on the frame/window. i've looked and can't find em, figured i'd just fab some sort of wire hoop from 1 piece to the other. Be nice if i could find it, but 1-you can't really see it unless you're looking, 2-when the soft top is on, you ain't locking the cab up against a determined person, 3-fixed the broken lock on consel so have that and glove box to lock stuff in like sat radio and fm faceplateI have the slider windows and one of the window locks are missing does anyone no where I could get one or how much they are. Talking about the the black piece on the window that clips to the frame to lock the window closed
