OK, coming back to my workaround for the shaft bushing.

So, since the 7mm bore / 9 mm OD bushing seems to not be in existence, I ordered 8mm bore / 10.6mm OD nylon bushing, which comes in qty of 10 for $5.

Now, thought I to myself, I need to diminish OD by 1.3mm (the original seems to be 9.3mm OD).
To do this I would have to cut a sector such that the outside lengthe would be 3.14 times that, which is about 4mm.

So, this is the bushing
   


This is the bushing with 4mm section cut out.
   


This is the bushing that now fits snug into the hole in the bracket.
   
   

An this is the shaft going through with good, not tight but properly restrained fit. Plus this nylon is more slippery than the original material.
