As you said in your post, you're going to do this job this week end?
Have you bought brand new cylinders or you're sending them to be rebuild?
With the shipping delays, I won't have the choice to use the car. So I will need to re-install everything et remove another time when I will receive the cylinders from the shipping. I hope the top will be able to be close securely without the cylinders in place.
I'm starting to read a lot from here and the web for procedures.
