Volvo Repair: Swapping sunroof / interior bits 700 / 900, donor car, type subject

Question
Hi, could you tell me if all steel sunroofs fitted to 700 estates / wagons are the same, as I would like to replace mine which is rusty from a junker / donor car. Also, are interior bits such as seats & door panels from a 900 wagon ok to fit into a 700 wagon? I understand that a 900 wagon headliner is a much better fix and an easy swap into a 700 wagon as it is better made, which got me wondering over seats and trim etc. Many thanks for any help, BTW I am in England, UK, so my car is RHD if that makes any difference.
