This is a genuine Toyota windscreen gasket for the Land Cruiser J7 hardtop models – fits the 70, 71, 73, and 74 series, including LJ, HZJ, and PZJ variants.
The part number is 63151-90K02, and it's a brand new OEM piece straight from Japan.
It's the rubber seal that goes around the front windshield, keeping water and wind out of your cab.
If your old one is cracked, dried out, or leaking, this is the correct replacement.
Installation requires some patience and the right tools – usually a rope or special tool to pull the seal into place.
