Yes exactly, we threaded the bolt back in leaving say 2 cm exposed and smacked the wedge off inside the end of the quill.
Not a wedge, flat round bolt, the old stem bottom end flat as well.
The bottom of the quill cylinder was cut 8 slots vertical 2 inches, the nut\wedge goes inside then flanges by forcing the tube slats outward.
Different fer sure, not seen by me before.
We're good to go, thanks.
