This is long over due. As time permits I'm going to weigh FD parts and list them here.

Please don't clutter this thread with anything but part and weight information.

Thanks!

1) spare wheel and tire with tie down, jack and crank, wheel chuck, tool styrofoam triangle holder with lug iron and the long wheel rod/bolt to tie down the OEM size wheel in the spare wheel location. The listed spare tire parts weigh 29 to 30 pounds. So if you remove your spare tire kit you will shave approx 30 pounds.

 

1994 and 1995 passenger airbag assembly. The fully assembled airbag weighed 10.5 lbs. The shell with the airbag and cartridge removed weighs 2.5 lbs.

The A/C condenser core (just the core) weighs about 5.5 pounds (I just happened to measure it a few days ago).

I will weigh the heater core and the HVAC unit (minus the blower assembly) when I get home. If I have time I will measure the rear seats again.



Edit: The central HVAC unit with the heater core weighs about 6.4 pounds.

 

Please keep the part weights coming

 

You'll know when you're done when it all adds up to 2800 lbs
