Weight gain for Dusters/Demon/Dart Sport from 1972 to 1973?

[MRGTX]

Waay back, before I found my Dart Sport, I test drove a '71 Demon that I ended up passing on due to some body work needs that I wasnt up to...

...but the Demon drove well and looked great. The thing that struck me when I eventually found the '73 Dart Sport was how how much more "stuff" had been added. Much bigger bumpers, bigger brakes, more substantial head liner/carpets/interior door panels... Possibly more sound deadening. Granted, some of these things may be related to the option levels of the cars I drove....but there seemed to be some big differences.

I loved them both but the Sport was the nicer specimen.

So did these A Bodies gain any significant amount of weight with the changes (assuming a cars with the same engines/trans options)?

I always removed the front bumper support from the backside of the 1973 & 74 cars (Dart & Duster).
I also remove the outer front bumper frame brackets as well.
Looses approx. 25lbs.
The doors have a bar in them, that isn't in the earlier doors.

The 73 bumpers are heavy and the 74 are even heavier. I lift 4 days a week and the rear bumper was surprisingly heavy.

Thanks, guys...so any detriment to removing that bumper support? Will the bumper fall off, for example?

So was the weight gain limited to the bumpers?
