Sony WM-D3 walkman


I am lucky to own a Sony WM-D3 walkman, but it seems the belts are broken.
The function buttons work, but the cassette tape won't play or Ffw/Rew :-(

Does any one has the mesurements of the belts needed to fix the WM-D3?
in cm/mm please if it's possible
(that's what we work with in the Netherlands)

greetings, Danny
