Lol, sorry it took me awhile to get a respond to ur question. Alittle bit here, a little bit there, but I'll tell you the major things.
Backseat section: 30lbs (noone is in the back and i haul stuff with it) Rear bumper inner support bar: 10lbs (the metal was rusted to the point of no purpose and the plastic "bar" was just sitting there...it squeeked like hell too) Rear swaybar and hardware: 6lbs (dont ask)
Headunit and speakers: 10lbs (blown)
Rear sound deadening: approx. 10lbs (i cant remember for sure)
There's 66lbs, the rest was smaller stuff.
I just removed the carpet and some of the front sound deadening becuase water got through a rubber plug and made the carpet nasty. Still have to weigh that but a good 20 lbs in that.
The rear bumper support? Get another one. Really. No except my mother-in-law makes a good crash test dummy. It's there for a reason.
The rear sway bar? Based on my background and my other posts you can guess....
Thou art EVIL

The car had some wrecks which damaged the brackets holding the bar to the car, then rust over the years weakend it, and the streets here are so bad, it finally fell off and was smacking off the control arms. Its not worth the money,time, effort to get all new parts and fab up new mounting pads for the body. Funny enough, the metro, my beater, had a sway bar but my nice cars dont. I need to install the one I bought recently on my 67stang.
I doubt a plastic bar is going to do much to stop a car from going up my asss.
