Fester,
Glad the source helped.
On a follow up question, was wondering if you can confirm you have the second flat spring steel wrap around spring (see
blue circled part in pic below) inside the thick collar that supports the back face of the pins along with the wire spring???
Can't see it from the perspective of your third picture showing the handle removed, but would note that if that secondary spring is missing, that would allow for exaggerated pin flexing and movement (along with the worn openings).
You may have to get a little deeper into your shifter/collar to confirm if that spring is there and functioning.
