It's hard to find on Google maps and they don't answer the phones, but they pay the most of any scrap yard around here. It's on Atlantic drive, just before the BenFranklin bridge. They got two yards, Ferous and Non-Ferous. The Ferous yard is at the end of Atlantic, closest to the river. The Non-ferous yard is....I think, the second/third left after you exit 676 and go under the overpass. Just follow the broken down truck loaded so heavy the rear bumper is nearly dragging the ground and you should be ok
Don't get too excited though, you may just be able to pay for that rubber plug you bought
I'd recomend one big trip vs. several small ones.
