I believe the wiki says that the parts don't actually weigh anything despite what your Pip Boy says. Otherwise (unless you are playing on PC, presumably), you are stuck with the things.
ug, well paint me frustrated and float me down the river that svcks.... I have no problem with quest related items that can't be dropped as long as there is some way to get ride of them. As far as I know no matter how you ended the quest you'd still have these useless parts in your inventory. Not great if your trying to roleplay and go "light" yet your inventory states your a packmuel with a dozen heavy parts on your back. Aw well....guess I'll just have to makeup some story about why my character insists on carrying them around. Thanks for the info. :shrug:
To westoftherockies: He's dead now and I hadn't realized that I couldn't sell them or dispose of them in anyotherway...I could reload a save but I hate that irradiated town so much I'd rather keep the parts and pretend they are not there.
