@ Tom
I get the parts from our US trip last year.
I bought the pulley from Jerrys Auto Supply, WA.
If I lock your and my pictures, both pulley's are on axis.
Mine have a space from about 2-3 mm in back but not 10 mm.
This 2-3 mm space is to less.
I think I have to produce a new one with the ~10 mm off axis to the rear side....
