Here is a pic of someone's 272 on stands, not "perfectly" located, but close. I aquired a 272 manual in PDF format from someone (online, but can't remember where it was posted.)
The locations for lifting slings as mentioned in a posting above would be 7'5" forward of transom, and 9'3" aft of bow. The slings should be 10'3" apart. O'DAY recomended that stands be located about at these points, with blocking under keel. I also attached that 272 Manual in 2 parts.
