the steering column is different too
the granada brakes use the same calipers as the sierra's with ABS
if you don't want to modify the geometry to suit the granada front hubs you've still got a couple of options:
you can convert the granada rear hubs to 4 stud just by swapping the flanges for sierra ones - and use sierra front hubs to match
or you can convert sierra front hubs to 5 stud by machining the granada hubs down to fit the sierra bearings and seals (they arn't even hardened - cost me £10 the pair), then you just need some 5mm spacers and longer bolts for the calipers so that you can use the granada discs
these are my 5 stud sierra hubs
