Ken and Jess,
Security Solutions in Bellingham has the Legge blanks. They are about the only place in the Puget Sound region we have found that carries them. They are located at the corner of N State St and Franklin St. The retail key shop is across Franklin (on the east side) from the big storefront that does commercial security systems. They made spares for my 88 CL and we use them regularly for brokerage and charter boats, so you should be good.
