I've got my ar cleaner installed and the breather is over the hole in the left valve cover, but what joints them? Is it all rubber hoseor a metal tube with rubber on the breather end? Looks like the rubber hose would have to have a 90 degree bend on it, but never have seen one, or found it in Ground Up catalog. Any ideas? The assy manual is not clear on this. Thanks!

a thin metal pipe with a short piece of connecting hose

A thin 90* elbow-metal, with rubber hose connecting. Hinshaw`s has them.

Dave, this is the correct tube for the 68 air cleaner to left side valve cover hose. Then there should be a molded 90 deg hose between the valve cover and air cleaner. It's not reproduced. The 90 deg fitting would be for the open element air cleaner, and would go to the right valve cover. Not correct for your closed air cleaner.

Bill, I happen to have one of the fittings that you show! Any ideas for the 90 degree rubber elbow at the top? I have a pcv hose with a 90 degree molded into it, but its too small to use on this. Thanks!

Get a water pump bypass hose for a short wp, and cut one end off until it's the right length.
