Sorry for the late reply. I am not 100% sure if i did have the battery cover or not last time, i got this one seconfd hand from ebay and it's a bit tatty but it will do. Sorry Alan even cleared out the shed today and found some real old OEM boxes but none for the disks.
All i know is they are Saab OEM disks 308mm. Your best option at the moment i would say is the LMF deal, I think i payed around £200 for mine but that was when LMF was way more then that.
I would also stick to OEM GM pads.
Hope this helps.
Jammee, Matt deff did his fair share of work.
