How worried should I be with this leak?

[Macca86]

Since Ive bought my SS there has always been a really tiny oil leak from the rear diff. If fact that minor Id only ever have maybe 3 or 4 drips on the garage floor a week. Car has had a fair bit of use over recent weeks and then has sat for the last 4 days in the garage. When I moved it out today I notice that a fair bit more oil has leaked from the rear diff (as in a circle about 10cm diameter on the floor and able to dip my finger in the oil) What exactly would be the cause of this and am I heading for diff troubles? I checked the oil level in my diff about 6 months ago and it was fine. Ill check it again tomorrow at work and see how it is now.

wheres the oil leaking from ? it could just be the diff cover gasket leaking ? or a washer on a bolt isn't there ?

Think its coming from the diff cover gasket but ill have to degrease it all and then check exactly where its from
