The COE had a normal truck road draft tube,I was expecting one longer but since the brace was not hooked up who knows. I am trying to make it look all original and hide the PCV,my plan is to insert a freeze plug in the bottom where it vents and solder a nipple to the road draft tube near where it goes into the block and then use a screw in PCV near the carb and run a hose down to the road draft tube around the rear of the engine. The tube from the COE had holes in it below where the brace was attached which seemed strange but after taking a 50 to 52 car 235 side cover off that was worse on the inside then out and the hood was shut so it must have been subjected to a bunch of moisture from the ground.
