I fitted a slightly later 1.4 one that had a lower final drive which helped somewhat - 4.54 vs the original 4.29 - but mine was a single linkage box, not the late 3 linkage, so my options were pretty limited. It was really only because the box was perfect inside versus looking at many that were half shot.
