First time poster! Dug out my original Star Wars toys that haven't been played with in about 25 years for my kids. The wings of my X-Wing won't stay open when I push down on the R2. Opened it up and saw that the blue ring at the base of the R2's dome is cracked and won't slide under the tab to lock into place. Tried gluing it but the force of keeping it under the button was too much and it broke again. Is it possible to replace the R2 with another one? How easy is it to remove the old one and attach another one? How do you do that? I'm enjoying trying to repair/clean my toys for my kids. These are just for play, not collecting. Thanks!
