Full disclosure: These front adjustable end links came installed on a used sway bar I purchased on eBay. I do not know who they are manufactured by. The donor car was a 350z but the bolts are too large and do not slide into my control arms. I would hate to toss them knowing that someone could use them. I'll take $45 shipped for the set. Light surface rust is present but the moving parts are not affected. Sold as is!
