Steve,

The cross member bolts in. You unbolt the old one, then have to put the new one in. My understanding is that some of the holes will line up, and some won't.

The thinking goes like this -- the spindles are designed to take the discs and calipers, so you want the spindles. The spindles won't work with the existing A arms, so you want them too. The upper A arm bolts to the frame -- the lower A arm bolts to the cross member -- so you need that too.

That brings up another question -- since the upper A arm bolts to the frame, the distance between the outside edges of your frame rails has to be the same as the donor vehicle, or you have to MAKE it the same.

Are you sure you don't want to buy a disc brake kit? These just replace the spindles with custome spindles that will work with the existing A arms.
