Faulty Left Channel

It doesn't cut the audio when I wiggle it

Off the wall suggestion. Remove some of the solder on the headphone jack link wires as if you were going to remove them. Plug in you phones and reflow the connections. That may allow the sections to "relax" and re align the contacts. You could try this first with the plug in if you wish. Will it help? I don't know.

I haven't had any problems with the amp since yesterday, but ive been looking into other headphone jacks. If I were to get the one in the link how would i go about wiring it?

Well, that's a mono jack, so you'd lose output to the right ear cup under all circumstances.  It's also not insulated, so you would put the chassis plate in the signal path which isn't ideal.
