Default Which NACA duct?

What NACA duct can bolt on to the stock front air damn of a 95 LT1? I have quantum spindle ducts and hosing, but the air inlets I ordered are way too big. I am trying to stay away from the $125 option. Will any of these work?

I don't remember how far the air dam sticks down, best to just measure it then pick a duct.

I have a Z51 so I used bigger ducts. I dont know what would fit in the smaller dam. Doesnt Quantum have ducts to go with the spindle ducts?

It is very short - less than 3 inches, so I was hoping somebody had found something that fit or altered it to fit. The Quantum ones are $125 for the air inlets, and I was just trying to find a less expensive way. I was going to give it one more shot and then just order the Quantum ones.

I see. The Z51 spoiler is a little over 3" long. You could try to fit a Z51 spoiler on and use the cheaper ducts. The side spoiler pieces are only like 15 bucks at ecklers.

You can make them for less then that too. It would just be a simple plate with a round hole, then tack on a tube or even abut the hose to the plate.
