Track rod for S2?

[LanciaFin]

Hello again,

Many sources offer the same track rod (the long one in engine room) for all Flavia models, even though original part numbers are different. Like here:

Are the differences really only visual, not functional? So the long track rod for Flavia S1 would fit to S2?

Best regards,

Ok, I've been informed that Flavia S2 needs to have its specific track rod. So far I've found some units for way over €200, so if someone knows a cheaper source, I'm interested.
