Replacing Oil Pump On '90 Ls

The oil pump on my '90 LS is leaking. On a scale of 1-10 (with rebuilding the transmission being a 10), how difficult is it to replace the oil pump?

Based on the number of steps in the factory service manual, it looks pretty daunting. One local shop quoted 17+ hours of labor. And another said they would have to pull the engine to get to the oil pump (even though the factory service manual doesn't indicate this is necessary).

I'm reasonably proficient, but certainly don't have the Special Service Tools that the service manual says to use for some of the steps. And pulling the engine in my garage is simply not going to happen! Are any of the SST's actually required?

TIA
