A couple of people have asked about frame defects. rust. etc. So I added some photos taken with the seat and tank off to show where the frame was drilled. All the numbers match as well as what's on the title. So I made a montage of those four and added that picture as well. It's titled as a 1975. but based on the numbers I looked up. that's wrong: it's a '74. To reiterate another question: I'm in Minnesota in the Twin Cities area. about 25 minutes West of the airport.
