Chevy Boy, Not sure why you are asking those questions. Of course I know why, because you don't know what you are talking about. See, if you knew anything about a 67 Shelby, you would know the Cobra Air breather base (S7MS9600B) had an elbow and Autolite hose that attached to the passenger side PCV on the valve cover. A lot of people cut them off because the original setup by Shelby didn't work well. I now have the correct elbow and original setup. Restored back to original. Thanks for your concern.
Whoops that's the base only I'm not positive but I think this is what your looking for S7MS6A664A http://www.fomoco.com/1967-1968-mustang-parts.shtml If that not it try these sites when you get time http://www.trophymustang.com/index.php http://www.autokrafters.com/index.tpl?cart=114878509677835 http://www.npdlink.com/ http://www.mustangsplus.com/Merchan...ore_Code=MPFMP&Category_Code=shelbyfiberglass Hope it helps
