disco sunroofs

hi can anyone tell me if the sunroofs on a disco 1 are the same as a disco 2?my disco 2 has been leaking for months and as i went to remove the rear sunroof 3 of the captive nuts that hold the frame in place are not captive anymore!so before i have to get brutal to get the sunroof out i would like to have a spare to hand just in case! i am also assuming that the front and rear sunroofs are the same?

300 series D1 & 2 sunroofs are the same but the later D1's and then D2 have some minor changes/mods to them ie. how the drive cables are fitted and the seals are slighty different but the looks, fitting and operation is exactly the same, front and rear sunroofs are identical.

And yes the brass inserts in the plastic do pull out complete with the torx screw, inserts and screws are not a listed part so we got replacement sunroof and frame.
I found all this out with a mates D1 when he changed is sunroofs and we took one apart which was interesting for the the bits, the bits we didn't use went on E...bay.

ideal,thanks for the info,best get ebayin as we might have a dry few days this summer to get it sorted!
