A few more photos of 5S140 I got from previous owner Gary Werner many years ago, I believe these were all taken in 1974. The current registry only has info on this car up to 2001...
Wow! Those pictures are awesome! Thank you for sharing. Do you know the number of the 66?
Minor detail (not really that important), Oregon's first year of the yellow with blue letters license plate was 1975. 74 would have blue with yellow letters. The green year sticker would have been 1978 or 1982. With a two year registration that puts the photos in 1976-1978 or 1980-1982. Not trying to pick, just trying to help. Awesome pictures!! Again, thank you!
