Master cylinder marring with pushrod?
 

My elise master cylinder came separate to my elise pushrod and I am wondering how they are marred together? I have 2 other master cylinders that I bought when trying to convert to non servo and the pushrod is held in place by a washer and circlip (the pushrod end having a ball end)

However the elise pushrod has no such ball end?

Anyone with experience who can advise?

Cheers
