er think should as on lwb go from b pillar to d pillar roughly
so on swb on this maths the b pillar is the a as it were and
they run full lenght of roof. might need adaptor at front
though to account for slope down to windscreen.
I can tell you for defo they will fit
I turned them round though for the curved foot to fit near the front screen.
Works a treat for me as I wanted it as close to the front as poss to carry the roof spots too :thumbs
If you want to carry big loads though, you may need a little support at the back depending where you mount them.
