If the arm is too short.. what's the best solution, just go back to the two point protractor? I can never tell if I'm close enough as it's so fiddly to line up!
According to Kenwood the KD-2055 is designed to be used with a 9.5mm overhang distance:
Effective length: 215 mm
Overhang: 9.5 mm
Pivot to stylus: 205.5 mm (effective length - overhang)
For standard IEC records a Baerwald protractor needs 18.6mm, Stevenson 16.6mm and Lofgren B 19mm overhang for an arm that length. If Kenwood's figures are correct you would probably struggle to align satisfactorily to any
universal two-point protractor as the slots in the headshell would be too short?
You could try printing an arc protractor for DIN grooves, Stevenson alignment and an arm length of 205.5mm? This would only require 15.6mm of overhang, but even if you can push the cartridge far enough forward to follow the arc you may not be able to twist the cartridge enough in the headshell to align to the grids (Kenwood didn't publish the original offset angle so I can't say for sure).
If this doesn't work it may be easier to source an original overhang gauge
