Weight difference between glass and steel bumpers on 71 duster/scamp

That is def. the wrong way to look at it. My all steel, all cast iron motor, full stock interior, full exhaust, roll bar, subframe connectored 71 Duster is much lighter than my 71 Scamp that has an aluminum intake, headers, short exhaust, gutted interior and fiberglass hood and front and rear bumpers. It's all about looking at the whole picture and getting alittle out of everything....

Not exactly sure what your getting at with your comparison?

My reasoning is just for the fact that I do tend to drive this car in the colder months of fall, and having the heater in the car is nice...If its not much weight savings, im not sure its worth it for me to pull it out.

Although its getting pretty cold here lately and im not driving the car much anymore. Going to take it for a drive tonight and see if I can survive without the heat...if I can, then its quite possible it will also get tossed.
