I’m looking for the longer of the 2 bowl vent rods that Holley briefly used on their 2300 series center carb. My one pic shows the shorter [more common] version of this rod above a fabricated longer version of the rod which my 440 six pack application requires. I saw several of these longer bowl vent rods at Carlisle this summer, but all were attached to a complete 440/6 setup. Thanks!
