Originals (or original types) are always your best bet, they fit as designed for a reason, depending on the "modern" type you get, they "Can" get sucked up into the outlet hose and displaced from the required position.....SO that is always a possibility with certain modern stat's. You can also find original (OR NORS) on Ebay "fairly" easily as well.....BUT where it me, I'd look for the "original" type IF at all possible. JMO
