What seals need replacing on the rear diff of a Mk1?

[mickburkesnr]

So my 1995 RAV4's been going great guns, until the other day when I noticed the exhaust back box looked a bit wet. On further inspection I get to see this:

From what I can see, the drive shaft seal on the left needs replacing as I think that's probably where the oil is seeping from. That said I would probably look to change the seal on the rear cover of the diff too. The other seal can wait I think.

Question is, does anyone have the part numbers for these two seals? Not financially able to go to Mr.T for these at the moment.

It's a Mk 1 1995 Toyota RAV4 3-door.
