You can also buy it directly from the dealer if you can't find it elsewhere. I paid $239 for mine and it came with a bag to store the hard top. I would suggest you to look into the ceiling mounted instead (wish I did before I bought the rack). The ceiling mount enables you to change your top by yourself. Whereas if you go with rack mount, you will need someone to help you to remove the top every season, and it can be a pain. Both rack and ceiling mount cost approximate the same. Go with ceiling mount!
