That's pretty much what I'm after, it goes inboard until the bracket the air deflector attaches to, about an inch in from the hinges.
I've never seen anything like that for a Disco - an almost impossible job as well for access without cutting huge swathes of external panel. I think Blanco above is talking Defenders not Discos!
Oh, well... I guess it's going to have to be the hard way, then.
I need to replace the roof after it had an argument with a tree branch, and the screen needs to come out to do that, so pulling the dash and doing that at the same time will keep me off the streets for a while.
