My car was in the shop - just got it back and I am completing my profile. RQB 3318 is the serial number. Bob Johnstone's site lists a couple of options for the bushings - thanks.
Short story: I went to school in South Bend from 66-70. In 68 I found the Avanti factory and would go down and watch from a viewing station as they hand assembled a few cars at a time. There was one that was school bus yellow with a zebra striped black and white interior. By the time I left I wanted on of these cars. Every 10 years or so I would look at what was available, but never pulled the trigger. Well I recently looked again and found this one that had a new engine, new paint and new interior at a very reasonable price. My lovely wife said "you've wanted one of these for 50 years, you better buy it" - so I did. Having a great time on the Eastern Shore of Maryland.
