on the 03 and up its a direct swap... remove your old one and install the shee axle... 3.5 inches wider.... thats a good price.. i paid 10 for mine, only cuz i know ppl
$50 bucks is a crazy deal. I would make sure that it is not bent from a wreck or anything. they go for about $100 really used. So i would check close. otherwise yes it will swap right over on an 03 or newer blasty.
Jump on it. Its not a bad deal, thats normal price for them. I paid 30 for mine but ive noticed that 50-70 range is normal. Check out bansheehq.com I bet you find a nice one over thier for cheaper than that price.
