A friend of mine has a 727 for a slant and was trying to find out if it was worth anything. I did some checking for him and apparently not worth a lot.
Good Morning Ulf! The 65 Coronet I had with the old style 318 had a 727 with no adapter. When the originbal 727 went I, I swapped in an early 70s with no issues (other than fabricating the shift linkage).
