needing 63 Fleetwood parts

[Georges63cad]

  Hello to all, does anyone know if you can get wiper refills only for a 63 Fleetwood or do you have to purchase the whole wiper blade.  Also, I know the plugs original number is R44S but hard to find. I read somewhere someone used a R45S  and there is a R43S. I really don't drive the car very much but when I do sometimes it's a long way, so which is the best one to use. I'm also having trouble finding an air cleaner filter. The part # on the casing for the filter was AC96C....I can't get close to finding that one. Does anyone know a place to get these parts at a decent price. Thanks guys, George

Note the WIX number is 42080.  WIX is one of the best you can buy.  NAPA sells WIX filters under their NAPA Gold brand, I am sure they can order one for you if they don't have it in stock.  BTW, WIX oil filters are also one of the best, also available under the NAPA Gold brand.
