Remove all bolts in the pan assembly. You may need to remove other objects that may obstruct the removal of the oil pan bolts. It would be a good idea to have the oil drained prior to pan removal. The oil pan uses a special RTV sealant instead of a gasket and can be a pain to seperate from the engine block. Use a soft faced hammer and strike the sides of the oil pan until it begins to loosen from the block. You can then use a screwdriver/prybar to seperate the seal and have the pan come off

The manual transmission does have an oil pan. Try tightening the pan bolts to see if any have come loose causing the leak

I don't know what size they are, but the sockets are available at auto parts stores. They may know the size or you could try a couple to get the right one. I hope this helps you.

If you use a good pair of vise grips you may be able to get it off if you adjust the visegripes just beyond your ability to clamp them and then proceed to clamp them shut with a large pair of channel lock pliers, if this does not work drill the appropriate size hole through the bolt and tap in a large easy out bolt extractor into the hole drilled and proceed to use a star socket
on the end of the extractor to unsrew the frozen oil pan bolt.
