Going to be scrapping out ZX soon (well MOT runs out today...) Or maybe that's on here (no, it's not a Xantia getting crushed, Doc!!).
Anyway - it has remote C/L and I have two working fobs. I think this is the same system fitted to the BX (square fob separate from the key, IR receiver in the roof, control box somewhere). I can strip this out if anybody wants to try it in their BX?
It also has a sunroof deflector - that MIGHT be the same size as a BX one. I'll try and get a measurement off it.
