How easy is it to add roof rails to a Discovery 300 series. (ie the fixed longitudinal rails, not crosswise bars)
I've seen them on t'bay, but wondered how easy it was to fit them.
Obviously one needs to drop the headlining, but it it then obvious where to drill the roof panel? (ie pre-positioned braces etc) or is it a completely different roof panel?
Is is just a case of bolting them down?
