Well they unbolt from the Volare but are then welded in. At least all I have seen have the frame rails cut to shape then welded in.
I really had my hopes up. It would have been a great way to raise it. It looks like my only hope is some custom fabbed raised spindles. It looks like there are a few shops that do this kind of work but it looks like most of them want to do the same spindles they have been doing.
