Rocky watch which one you look at getting...I got one for the Satellite from Ebay...It didn't have a billet neck and you can actually put the radiator cap on and turn it past the stop point as the aluminum is too thin. I bought a Champion 3 row for the Dart from a member here...it has a billet neck and it seems to cool better than the other one. I actually need to order one for the Satellite from Champion too...
