Many thanks for your replies 👍👍
With the dimensions from Powertrain Industries (32.0 mm x 106.3 mm) i found U-joints listed as IVECO Part.-No. 4576888, available in the EU.
Unfortunately, after dismantling and cleaning i noticed the splined end in one half shaft is worn. I didn`t feel the excessive backlash with the shaft in the car, but this should explain the drivetrain swinging/rocking while going at constant, moderate speeds.
