Hi there, anyone know what roof bars I need to fit '07 Zafira with solid rails front to back. They have the 3 sets of 2 holes on the inside face. Wondered if I can fit different bars which do not locate in the holes to allow more freedom on position ?

Vauxhall tell me I need 93199522 but this seems pricey at 100 quid.

Cheers, Mike
