Hi m8, sounds interesting - any pics to post up in the resto section?
We love to see progress!
The clean sunroofs do come up occasionally but are well overpriced usually.
My friend just picked a mint one up from a non-rs breaker very reasonably, so you could try that route (no rs tax).
Or, if you are feeling brave you could look into this

If you are doing a full resto, don't forget to check all around the spotwelds holding the sunroof support in, as well as the rear of the support.
