Upper vent wing pivots

Not sure if this is the right forum for this but does anyone know if the upper vent wing pivots are the same for an A body and a B body. I can find them for a B body but not an A body. I really only need the grommets or seals (whatever they are called) that goes through the hole in the vent glass, is there a source for those out there anywhere, I have looked but not having any luck. Thanks for any info.
