Starter wanted

[BJ401976]

Hi
I am i need of a starter for my B motor or suggestion on where to rebuild it. ive tried to get it fixed here in Stockholm but with no success. I need to replace "anchor wiring" not sure if it the correct term but it is the inner and outer copper wiring inside the starter. Since the BJ 40 never were sold in Sweden it is really hard to find parts over here
Thanx in advance
