ECZ - B intakes for what ever reason, don't have the front vacuum hookup found on 2 bbl intakes, so who makes a carb spacer that includes a place for fitting the vacuum line?  And what thicknes is the spacer?  It's for a 57 Ford & a thick spacer, I" or more, may not allow hood clearance for a stock air cleaner.. ( I should have thought of these issues earlier! ) And yes, I'm aware that there is access at the rear of the intake, but Ive been advised that a hookup of a PCV there is not recommended, because of a possible lean mixture issue . Info appreciated.
