Yes, like I said... a probe (there is groove in the piston boss for that purpose, but don't reuse them..
If you have new ones use them, but I've reused them "many" times. Mostly out of need. One of the new one's went flying, never to be seen again. I've "never" had a clip fail. I have forgotten to put one in and had a failure though!
