That's mainly wrong ! If your dizzy requires an 'asymetrical' cap, you shouldn't use the symetrical one as it will cause misfire ! And: It's possible to get the 'wrong' one type fitted to every Bosch housing when a PO possibly 'modified' the clamp mounts over the years.

BOSCH caps are not engine capacity related but only distributor related. For 105/115/116's series w/Bosch dizzies there are 3 different caps available - 2 of them are of the 'asymetrical' type and are interchangable.
