Like the title suggests, post the weight of parts you might happen to have lying around or wanting to pull off your car. My goal is much similar to the definitive engine weights thread, which is to gather RELIABLE and VERIFIABLE information. Please include as many details as possible. Just as you shouldn't post an engine weight without sharing if the flywheel was on or not, please include all that was on the part. Example: Don't give us a hood weight without specifying if that includes the hinges, springs, etc. I expect honest measurements, not just guesses. If possible share how you weighed the part, and if it's quite heavy (like an engine block) please be sure you're using accurate measuring devices that have been zero'ed.
Since I'm starting this, I'll go first.
Rear Bumper: 25-26 lbs
Scale Used: Reliable Bathroom scale, measured 3 times for consistency.
This weight includes the main steel box frame of the bumper, the rubber cover, and the chrome cover that goes over the steel box. For those curious I'm including a picture of what the inside of the rear bumper looks like, so you know what makes one up.
Dash: 20 lbs
Scale Used: Same as above
Includes: Metal Frame, Padded Cover(stock, no carpet or cap), Center Cluster, Cruse Control Switch, Rear Wiper/Dash Light Dimmer Switches, Air Vents
Does NOT Include: Speakers, Center Gauges, Dash Support that goes across car (I believe the steering column is bolted to that piece too, anyhoo, it's NOT included as part of the dash here)
I hope to have more input in the future, and I hope others have some stuff to contribute. I have good guesses as to what things weigh, and sadly many things I no longer have spares of sitting around, so I guess it'll have to wait for another day.
