In addition, i've read on the 80/90 forum that the wheel opening is in a
different position on the B4 fender, so if you fitted a B4 fender you'd need
the B4 suspensino geometry for the wheel to fit in it "properly".  iirc,
the wheelbase changed between B3 and B4 ?  Or at least the fender and susp 
geometry changed such that a B3 car with a B4 fender will have the front
wheels too far forward or too far back to "look right", and might also cause
real issues apart from just looking wrong.
