2003 convertible piston replacement parts

[hotcars26!]

When I was putting my convertible top up on my 2003 Thunderbird, I heard a pop and the passenger side of the top would not assist going up anymore, I had to help it. I got to looking at it and that piston part is supposed to sit in part of the mechanism, but it popped out due to the lower portion of the piston. Plastic is broken away, and the nub won’t stay in there. Any ideas on how to fix her where to get a new part if needed? Thank you so much for any advice.
