I'm in the process of converting my Elise to the Exhige scoops. Have looked thru the many posts on this, but have one question: the only source for the washers that fit the scoop seems to be Eliseparts, or Lotusgarage, at $6.50ish each. Has any member come up with a less $$$ alternative? I can make up something with trim washers, but nothing quite as nice as the stock part. Thanks!
