Air diverter valve - Need help FAST

[83burban]

I have an 83 suburban - c10 witha 350. While replacing the air pump last night i broke the air diverter valve (broke the little air nipple that reads manifold vaccum) the car is running rougher at idle and I can attribute it to that. To get it back on the road i drilled the nipple out and drove a roll pin into the hole and sealed it. The car still runs rough but it is better than not having it.

The air diverter valve on the car has 3 outputs - 2 to exhaust manifolds and a single line that runs to the air cleaner.

My questions? Can i find a replacement anywhere? Gm has disconituned that part number so no luck there...and parts stores only seem to have the diverters with 2 outputs rather than the 3 that mine has.

Can i swap a diverter with only 2 outputs - I have found 5 locally but none with the 3 outputs. Will the lack of the third output affect anything? My car is a california smog equipped truck if that matters.

I need the get this fixed fast so that I can get some road teast miles on it before I drive back to New York for school so any help is appreciated. After a brake master cylinder I will have replaced just about half of all sensors and all mecahnical parts.

Thanks for the help - Kurt
