Here is a link to the item at Sears: http://www.sears.com/national-set-of...2&blockType=G2
I ended up with two packages. Swapped one package into my garage door and its not nearly as loud as the crappy old steel rollers. These come ready to install and fit a standard 2 inch track. Very easy job, only takes a few minutes. Save yourself a couple hundred bucks and do it yourself.
$15 cash for pickup in Groveland, MA. Still unopened and in original packaging and could mail for additional postage fee. PM if interested.
