The offset washer which holds one end of each torsion bar (total 2 washers per beam) seems to be 5153 12. I can see that another version of the same washer is 5153 19 but this described as the version for a 205/309/206, from some googling.
Does anyone know if there is any difference between 5153 12 and 5153 19? i.e. are they different sizes?
It's just that 5153 19 seems to be more readily available, which would help...
