About 14 years ago or so, street rod builder magazine ran a tech article on how to build a smaller scale Cadillac style aircleaner out of an aftermarket aircleaner and exhaust tubing. I can't find the mag anymore, does anyone have a copy that they can copy off for me?
http://www.jalopyjournal.com/forum/threads/tech-day-kustom-made-air-filter.128921/ This should help a bit, very similar design, I'm sure if you have the skills to do this, you could do the Caddy cleaner with a little modification.
