Emission Decal question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Is there a way of finding out what emissions decal I had on my truck originally? I don't have anything under the hood concerning vacuum hose routing, etc. I'm having to put my cannister back on, and need to know where the lines go, and where to connect them on an Edelbrock AVS2 carburetor.
It's a 1984 GMC Sierra 2500, 350, TH400,2wd originally sold in California. The exhaust manifolds have the holes for the air tubes plugged with what looks like factory threaded plugs.
Thanks
