As others have indicated - 
Series and 90/110/Defender windscreens are different, and the roof is different to suit, so no, the roof won't fit. The rear cab section is interchangeable, although the lip for the door seal has a turned up edge on the series that is not there on the later vehicles to fit the different seal - if fitting to a Defender, this can be ground off.  The rear window is different but doesn't affect anything else.
A possible problem is that the upper seat belt mount is in this rear cab section, and depending on the age of the Stage 1 may be different from the Defender - it will probably work, but there may be legal implications.
If possible make sure you get ALL the fittings - they often seem to get lost when cabs are removed.
