Direct Cool Air to snorkel

I never did that mod to that car but it looks simple, if you have the factory air cleaner just get some flex duct hose like from pepboys and duct it together,
you can go to a junkyard and get a air scoop off of just about and car or truck, just select the style you want and check that it will fit the rad support hole
If you have a aftermarket or you want to change it all over then look again at a junkyard and pick up the whole air cleaner assembly that will look good in your car. Ther are many ways to do this
