Are all air-gap intakes the same height?

I ran an eddy air gap on my 68 barracuda. It is close. I had to run a dropped base air cleaner to get it to fit. Then the base can interfere with the linkage slightly. More the throttle pressure linkage than anything else. You will/should adjust where the throttle cable mounts to the manifold. It needs to be about 3/4” higher. Also the angle of the throttle pressure linkage might need tweaking or adjustment. One issue I had was I was running the stock lid. The dropped based air cleaner brings the lid down towards to carb throat more than I would have liked, but ran fine until I went back to the stock intake.
