I wonder what a repro 70 Barracuda steel fender weighs compared to an original?

Also the cheaper chinese/south american front glass windshields are thinner and weigh less. Look for non-PPG front glass.

There is some no name reproduction side glass that is thinner too. Troy got some off E-bay for a 68 Dart that measured thin. Made in Brazil, IIRC.

One mans cheap reproduction parts are another mans trick lightweight race parts.
