Rear Window Slider Seal

Hey ya’ll, does anyone know if the center portion on the dual slider window where it latches could be repaired? The owner before me pit tons of holes in it from i’m assuming locking themselves out. Don’t ask me why they didn't use the same pinhole that’s beyond my pay grade. Whatever they did they mangled the crap out of it and it leaked horribly when I first got the truck. It would really suck to have to replace the entire window or even just the sliders if that’s possible. I’ve had the center rtv’d together for a couple years now but it would be really nice to be able to open it. Thank you to anyone who can help me out and God Bless!
