Thanks! It seems there were a lot more of the silver with tri-shield produced, so over the years they ended up on lots of wheels.
The cap for the '66 to '70 is entirely differnt. It has fluted sides, not the smooth chrome of the 71 and newer. I even had the wrong caps on mine for about 10 years. They were all I could find.
Glenn at parts inc is the guy to talk to if you phone them. He has helped me find a lot of hard to get parts. They got 2 '67 electras in their parts yard about a month ago, and there are lots of parts there. If you need any particular part, let me know. I have a few spares.
I still need the Electra 225 script for both quarters and the trunk lid if you run accross good one. They are seperate pieces (Electra and 225). I have 2 '67 converts. One red, one blue (28,000 mile original).
