Clutch cover seal replacement?

[SpidyJ]

So,

Just took the leaky slave cylinder off........I think I should replace the oil seal on the clutch cover where the (lifter) rod goes through.  It looks worn and is wet.
Do I really need the special tool as described in the shop manual or can I just pry it out and use the correct size socket to drive in a new one?
Is this a DAQ?

thx
