Sector shaft measurement? (1 Viewer)

Does anyone know the difference in the 80 vs 105 thickness? Not sure if the po of my 80 did the upgrade. The box has been ported for hydro assist.
Thanks

The shaft is the same thickness at the box.
80 series shaft is necked down to the pitman arm, 105 series shaft stays the same diameter

Looks like it may be the 105. It’s a bit twisted from a minor accident.
