Yee haw! The Island gets funny when it gets cold.
But seriously, I checked availability for a windshield frame in Germany.
181.847.401
Still available! That's the top half and sides of the frame, not the hingey part. That one is unavailable.
The top part would work out to about $350 Cdn. + shipping.
Although the Iltis has a different part # on the frame. 183.847.401
The glass is the same though.
