Mike, I thought it was a first generation floorpan when I saw the one pic in the Craigs ad that showed the narrow top sill of the back seat. I posted a reply on the Samba to I think your post, but I guess Everett deleted it because he doesn't allow discussion of Craigslist ads.

Do you know if the yellow body has been sold yet?

Did you ask about the original owner and whether there's any chance the original windshield frame still exists?
