I've just been trying to install my new 6" speakers in the back of my gen1 lib wagon just net to where the shockies are attached and came across this:
Top view of shockies/speaker position -

Random cord -

...You're looking at the silver (aluminum?) tub which wont let the new speakers in with a slightly bigger magnet.
It's only next to the right hand shockies and not the left side, i was just wondering if i can pull it out and thats its just old Air Suspension equipment?
Whats the Random cord aswell?
cheers,
