Ok guys and girls. Here I have a factory 68-69 4bbl intake (casting # 2806301). Here is my issue, while dry fitting a Carter AVS to this intake, I noticed that there doesn't seem to be enough clearance for the factory choke stove. The (choke side) of the Carter appears to sit and cover the front bolt hole for the choke stove. What am I missing here? Do I need a spacer? I thought you could get an AVS on a 68-69? Thanks for any info. Rob
