While Victoria British and Classic Sunbeam both list air-filters if you have the original you can take the two plates off and then use a WIX 4-2032 (NAPAA 2032) with comparative ease. The 2032 comes at about $5.50 and, while it is slightly smaller in radius, it is taller, but will still fit without hitting the firewall brace. The height more than makes up for the radius.
