Somebody used to make a "budget" cai like you're describing - open element filter that attached directly in front of the MAF, and had a heat shield/bracket, and retained the factory rubber tube between the MAF and TB. Pretty sure I saw it over at latemodelrestoration.com if ya feel like checking.
Otherwise, budget cai is as follows.... Go to AutoZone or whatever and buy a stock replacement K&N filter, remove the rubber snorkel thingy from the side of the airbox, remove the air silencer screen from in between the MAF and airbox, and then put everything back together with your new filter installed.
