Ok, had a top lift cylinder that was leaking at the top and a board member mention to pull out the o ring gasket with a dental pick. I just did this and realized it was a cotton packed o ring gasket. Can I replace this o ring with a rubber one instead? I pulled it out already and pulled it off the rod to go match it up. Has anyone replaced the top o ring gasket on their skylark or comparable convert? What is the easiest way to get it back on there now? Please let me know about everything!!! Thanks, Brian
