I searched rockauto and don't see and hoses specific to this.  Bschelle has the right idea.

It is the hose! I dropped the AC compressor and when I pressurized the system I could see the hose leaking. How do I drain the radiator? The FSM says there is a petcock on the right bottom of the tank. No there isn't. There is a nylon plug on the right tank but it is half way up the tank. No way will it drain all of the coolant. I do not see how it even works as a drain. What am I missing? I am trying to avoid cutting the lower hose if possible.

There is a petcock on the lower left of the radiator.  I believe it screws inward.  The guru used to say, cut a broom handle down to about 6 inches, cut a groove into it and use it as a tool to turn the petcock.

That is good news!  Use a silicone hose only

If you cannot find or get to the petcock just take the lower radiator hose off at the radiator. 

Might be more messy but less likely to break on removal

If that radiator has been replaced it may be aftermarket. And not all aftermarket ones have petcocks

I just looked at the 91 FSM and saw this.  I may have been confusing my NS and 4.9 platforms.

I assume they mean right tank from the perspective of the driver.

Hope this helps

yes it is. 

Turn it a quarter turn and I believe it pulls out.

I like the hose idea better though

That isn't a GM radiator.. loosen the drain plug and pull it in and out to see if its plugged.

I will be doing the deed this week. I am still going to cut the hose. I do not want to take a chance of messing up the radiator.

It is fixed. I dropped the a/c compressor to make it easier to get to the hose. I used 3/4 silicone heater hose. I also replaced the lower hose. I cut it to drain the system so I didn't have to mess with the radiator. I have not had the a/c working and I installed the compressor without the hoses just to avoid trying to find a belt to work bypassing the a/c. It is now just dead heading to keep the stock belt.
