it always clears the gearbox, even when the wrong way up. its just not the rite way to do it. the ford job sheet says you must drop the subframe and fit the bolt the correct way around, for two reasons, one, its possible that the bolt can rub on the gearbox casing (i know of genuinely loads of people who have put the bolt in the wrong way around, and not ONCE have i heard of it actually touching the gearbox casing), and two, not dropping the subframe to fit arms, can pull the subframe out of alignment. now that i do agree with, as its happened to me, and others. the car drives like a pig, and starts eating tyres, but i find this is after the car has had a good few sets of arms fitted. when i replaced mine recently, it had the original ford arms, with all the bolts the correct way around, i fitted the new arms, with the bolt on the gearbox side the wrong way around, that was over 1k miles ago, and the car still drives straight, and i dont have any uneaven tyre wear, and mine is lowered 40mm, and running 35 profile tyres.
