So it wasnt the start I expected to owning the new lever, had an almost 3 week wait for parts to get the machine up and running.
Acs sent out the safety system sleeve and also the original style sleeve.
When switching between the sleeves you need to swap the end of the piston.
You also need to adjust the spring length. To move the height of your piston, the safety system seems to sit lower in the group.
This is the stock sleeve/end combo as you can see it extends past the shower screen, to solve this you wind the nut holding the spring till it stops, before doing this measure or count the threads for the safety system, that way you can inter change the sleeves.
