Carb is from an '82 chevy G20 with a 305
I'm trying to follow along in the rebuild book, there are two gaskets (One thinner and one thicker, but they have the same layout) that can fit between the air horn and main body. I already have everything else cleaned up and reinstalled (getting the piston arms to seat properly with the plastic splash guard in place was a PAIN!) and I don't want to put the wrong gasket in. This wasn't described in the book!!
Also, installing new rivets on the hot air choke was STUPID! I ended up using small nuts and bolts to retain the cover.
