I need a full sunroof mechanism for an escort mk4/orion mk2.

I think they came in XR/RST's and as an option on other escorts.
Mine has completely rotted away so I dont want a rusty knackered replacement. The rubber seal can be crap as I have new.

This is pretty urgent, Im driving my orion round with a sunroof held on with tape!

What Have You! Thanks!
