Originally posted by shyrsio there is a guide in the forum about this procedure performed on Konica AR mounts but not specifically on this lens.
When I searched for the guide you mentioned, I could only find conversions where aftermarket lenses (Vivitar, etc) were changed over to K mount.
Those lenses were designed around a front end that was more or less universal, and the rear end was built to make it work on a specific mount - this means the actual mount, the flange distance, and the aperture linkage.
Shortening up the longer Konica rear end, and then putting K mount on it is certainly possible (although you obviously lose auto aperture) because there's "meat" to work with on the longer Konica rear.
Unfortunately, genuine Konica Hexanons aren't designed around a front/rear assembly system. Shortening up the whole shebang by more than five millimeters, especially on a short lens like a normal or wide angle is a real headache.
