Sliding Side Windows for Defender 200TDi/300TDi and TD5 (Dark, Green & Clear Tints) - PAIR

IMPORTANT NOTE: We have two variants of the dark rear side windows - to fit side window apertures with 70mm radius bottom corners (for most post-2004/5 Defenders and Puma/TDCi Defenders), and also 50mm radius bottom corners (pre-2004/5 200/300Tdi and TD5 Defenders).

This listing is for the version with 50mm radius bottom corners. You can still purchase these if your vehicle has 70mm radius bottom corners in the aperture for the window, but you will need to cut them out to 50mm. The 70mm version window is here.

If your Defender is a hardtop and does not currently have rear side windows then either of our 50mm or 70mm side windows can be fitted irrespective of the year of your vehicle.
