1. removing just the clutch cover, nothing flies.
2. When you remove the entire r/s case cover. do it step by step. which involves step 3.
3. BUY A MANUAL.
4. don't bother buying gaskets. they're a waste of money, instead, buy this

Run a light bead, using the brush. It won't stick bad when removing again and it peels off with your finger nail. Just make 100% sure you remove ALL the old gasket from the case and cover before replacing cover again. or you will have a leak
4. Be sure to drain all fluids. Coolant in the tranny isn't kewl. The gears really don't like water.
Then while you're at it, buy a decent dial caliper (@ $25) and you can mic your clutch friction plates and get the minimum service specs in the manual. That way you can get frustrated, ( great..more money...DAMMIT) like me, and know that's just something else you need to buy so you don't have to tear it apart again later.
