AW71 accumulator mod - 2nd piston has no top. Can the mod be done?

While my buddy and I were pulling apart the AW71 for the accumulator mod, we noticed the second piston doesn't have a sealed top like all the others we've seen in tutorials.

The piston is out but as you can see, number 1 and 3 are sealed. 2 had a valve with a hole in the top. Is this going to cause an issue
 
you're going to have to get better pictures. there's no valve in there. some years have a helper spring on the bottom.
 
Doesn't really matter what the face of the piston looks like, 2 of 3 should have helper springs on the valve body side, like in the second pic, one does not. You still need to pull all 3 pistons out, put bolts inside the springs inside, put the pistons back in, and reassemble.

This is what I was hoping to hear. Okay. I was afraid that 2 having the hole in the top would cause a problem versus 1 and 3 being completely sealed. Thank you for the confirmation
