I recently replaced my front and rear springs (with 14,000 miles on them, about 13950 of which was highway driving, and the rest just dirt roads, and NO four wheeling), and now I have the stock parts (springs, rear leaf block, etc) laying around taking up space in the garage. Anyone ever sell them? Is there a market for them? Would they fit on a regular F-150 if someone wanted to upgrade? What's the going rate for this stuff? If nobody ever buys used springs, I guess I'll just take them to the metal recycling place sometime, but I'd rather sell them if possible! Thoughts?
