OK, I think I see what you have now. That vacuum switch is mounted on top of the control, right? I'm not sure it is available by it self. Try at a Chevy dealer. Other than that, it's buy a whole control.

Yes Sir it does... I tried my local Chevy dealer today. No luck. I think you may be right. Looks like the diverter box is hard to find too. May have to buy both new... 
as if I'm not broke enough right now. But I have to fix it.. Ya know.

First of all Thank You this is the best site.. I just left that site too. I think I will just order both parts from them. I'm just wondering if the vacuum switch I need will come with that Unit. Mine is a two port...

It looks like it is on the top of the control. Call them and ask. I'm sure they will help.

Ok I'm all done. For the most part. Here's what I replaced all vents, a/c heater control unit diverter box and hooked up all vacuum lines. I know I really didn't need to hook up all the vacuum lines "I'm not running A/C" but I was under the dash so why not. At least the door on the kick panel opens and closes as it should. Any way here's my question. When I switch from A/C to heater the vents stop and the air is diverted to the floor and defrost. Is that correct? When I switch from cold to hot it blows still through the vents... It just gets hotter. Is this right? Inside and de ice I can't really tell what it does other than close the vent doors. I'm about 98.9% sure it's hooked up right. I really took my time. I have never had it working right so I have nothing to compare it to. Does this sound right?
