Sway Bar Upgrade

[RonB]

With Mercedes using many parts interchanging  with 108 - 113 & 111's. 

Does anyone know it the sway bars are the same between different models and are the thickness the same in all units or different?

If they are interchangeable -  [22mm - for 113] could one upgrade to large sway bar on the 113?

The 230SL sway bar is larger.  19 v 22mm I think.  Need different sway bar bushings.  I have this set up and like it.
