No, not a standard plug. Can't seem to find it anywhere. Tried Napa, Sanel Auto Parts, Fisher Auto Parts, Fastenal, Fasteners Warehouse, have a call in to Andy bernbaum I have had no response in a few days. Checked online, and also talked to some old Chrysler mechanics, and have had no luck finding one. Hate to replaced the whole tank at $400 when all I need is just the plug.
