**DRIVER's side Sliding Window ONLY** Not selling cap or truck. Take off from a Leer100XR cap. Cap it came off is on 2023 F150 short bed. So it will for sure fit Leer 100XR caps built for 2021 -2026 F150 short beds. It might also fit other caps, I don't know. Great condition. Locking, tinted sliding glass with screen. I replaced with a Windoor. I'm only selling the driver's side sliding window, not the entire cap or truck.
