Front consul bush which way do they fit Mk1 1.2htp

Hi Got to change my sons front consul bushes on his mk1 1.2htp and the old bushes are so worn so not sure which way new ones fit. I think the narrow slotted section in rubber is vertical and hex section has to be horizontal but they are offset so is it the narrower side or thicker side that is nearest engine. Photo from internet as example and his are about the same.

Going to replace swing arms etc at same time. Using Febi reinforced bushes.
