Dana, I don't know if you got the email I sent you a week or two back but there's a guy around here w/ a '65 Beaumont ragtop for sale..
I've never seen it but is supposed to be a NOM SB Glide car, his daughter's summer driver and I believe under 15 thou?.
Should be fairly low production and easily documented through GM Canada..
I know it's not close to you but let me know if any interest and I can get more info etc..
~ Pete
