I have a question about the air cleaner bases to. I have a base that I think it cake from a T/A but not sure. I've had it for a LONG time. It is the typical 16" base with a single snout. The end of the snout is about 3 1/2 inches wide on the end & it has 4 of the vac. hose clips , with the indentation on the side of it (where the dist sits) Has a place for 2 sensors on the inside of the base, 1 is for a sensor with a single hole post, & then 1 with 2 posts , both would come through the base for vac. lines to be attached. Also has the 1/2 or so hole for where the air port on the top of the cabs would come through it. Can anyone tell me what this base should fit. The smaller snout end is what is confusing me. As i said I've had this for a long time & am not sure about it. Any help ?????
