I can't seem to find a replacement grommet for my 2000 GT driver side valve/cam cover breather. I found the passenger side, PCV grommet on AM. The breather grommet is a bit different than the PCV. Also not sure if it matters but the valve covers are BBK 11 bolt, driver side oil fill. If memory serves me right I just swapped the factory ones to the new valve covers???. Any ideas on finding one would be helpful.
