3,5mm jack not working!

Hi, I got problem with my old 5th generation video 30GB iPod. The hole for 3,5mm jack is not working correctly >> the headphones (or whatever) are playing only for left side. The right side is just dead.

Is it possible to make it wokrking again ?

I've already replaced my display on this iPod once..but I guess there is no way to buy this small metal silver like part for 3,5mm jack ? Also the problem is that this part is fixed by a lot of glue... Is there some way to fix this ?

Anybody got some ideas / experiences ?

Thx a lot.
