Can you remember if the back of the hub (where the studs go through) if it was a flat surface? I thinking about redrilling the pcd so I can fit some 114.3 or 108 wheels.
IIRC the studs can be removed with the Hub in situ. There should be a place which is cut out, you line up the stud and then give the stud a whack with a lump hammer and bobs yer mothers cousin
