Funny how Napa works sometimes. Their internal systems are not great, especially up here in Canada, so it's quite the ordeal to get parts ordered and picked up. I live in a small town so these were not in stock. I ended up getting the generic 6651038 because that's all there was in stock. Had to make a few small mods as it was 1/4 instead of 10/32. Used the original plastic nut though and just forced a larger thread through it.
