The only 'odd' bolt the factory service manual lists is the one you have to access through a hole in the frame rail. I may have to take a closer look at mine.

Been there... done that. Had that same heart attack that you had. It'* good to hear that you have got it all finished though. It took me somewhere around 8 hours... i started in the morning, and didn't finish till it got dark. It'* a pain, but the way i see it.. we saved about $300 bucks in the process.

Ditto. It'* a repair that you won't likely forget if you have to do it yourself.
I couldn't believe it when I saw where that last water pump bolt was located. It took me about 5 1/2 hours to replace the water pump on my '93 SSEi by myself, and I hope I don't have to do that job again anytime soon.

Removing the torque axis mount is no big deal compared to the amount of work requred to remove the accessory bracket on that supercharged series 1 engine.

I even called the dealer and asked a tech about this when I had mine all apart and didn't see an easy solution for removing the water pump. The tech said this engine is one of the most difficult GM engines to replace a water pump for...and he said that they charge about 6 hours of labor to do that repair.

Good to hear that your replacement was successful.
I hope you were careful when you re-inserted the heater lines into the block. Even though I was careful when I did mine, one of them (the upper one) developed a slow coolant leak a few weeks later. I ended up having to remove it again and replace the o-ring.
