Hey, guys, not sure if this is the right place or not. I've found the information on cleaning, but I've a more specific question. I bought a loose G1 Jetfire with a loose arm. I've taken it apart and it looks like it's missing the screw that the two upper pieces of the arm clamped over, as well as the black ratcheted piece for the joint. Where would I go about finding something to replace this with? Is there anything comparable I can use from more current toys, or should I just keep an eye out for broken Jetfire's on EBay and mix and match pieces? Also, the backpack is kind of floppy - something I remember happening with my first Jetfire some twenty years ago. If I punch the pin out and remove it, what's the recommended way to tighten that particular hinge?
