Got a full set from Mike Satur for both doors, all stainless including new pins.
Worked well on the driver's door, but at the passenger door one of the three 13mm bolts at the inner part of the hinge did not move anyway.
So I had to try to remove the old pin in situ, using some extensions from my toolbox together with a 500g mallet. And this was also the way to hammer the new pin in place. It works!
