k&n for stock 2000 air box???

["A Jacobs" <Legal-Z@worldnet.att.net>]

looking for a replacement filter for my 69 2000, and i was wondering if
anyone knew of a performance replacement unit.  preferably one that is
washable and reusable.  i don't want to replace the air box because i
autocross in c stock and i don't think that is allowed.
thanks,
andy
p.s. thanks to everyone who helped with the rear axle seal problem-- and
especially mike poorboy who always seems to step up the minute i have a
problem.
