Default Rear Differential Gasket Source in UK?

So, next on my list is draining and replacing the gearbox lube (sorry, Jim M!--call me superstitious...). Mine is a 92 900T, with no drain plug, and i have no idea whether the lube has ever been changed, so I'm thinking to go through the rear differential cover and clean out the screen while i'm in there. But I need a replacement gasket, and can't find a source for one online. Anybody have any leads?
Thanks,
grim.

I've got about a dozen that I bought at an estate sale, don't mind posting one to you if you can't find any closer

Thanks, NE Swede! I'll let you know if I have any luck closer to home.

Meantime, if I empty the gearbox from the differential cover, how much gearbox oil should I expect to need to refill?

I believe it somewhere in the ballpark of 3.1 Quarts ~ 3 Liters

Thanks. I realize that is the specified volume of the gearbox, but I've seen numbers around this site as high at 6 quarts/liters, and I didn't know whether I'd get more out from the back than I would from a drain plug, if I had one. My last 900 was an 87, and had a square plug.

The maincase is 2.7 litres and the primary case 0.3 litres total = 3 litres

You won't drain much out of the primary case unless you park it on a hill with nose up and leave it for a decent while. If you do this you then need to prime the primary case by adding 300ml in through the breather port at the top of the case.

Try Neobrothers or failing that Dave at Warwick Saab Centre in New Southgate. Thats where I got mine from. But you may find you don't need it, buy some Loctite 518 from ebay.
Also ask him about the original Saab thermostat.

No love on neobrothers (though they do have the OEM thermostats listed...). Perhaps I'll ring up Warwick. Thanks for the tip.

You'll probably find the gasket comes off in one piece and is reusable. It's fairly thick and durable. As extra insurance use some loctite 518 on it. It's always worked for me.
