The fabricated front upright bolts to the same mountings as the original strut, which has a much longer moment arm. There shouldn't be any strength problems.

Designing the upright presents an almost unique opportunity to specify the ideal geometry for the application (well unique to us mortals - Ford always do it )

The designer can specify caster, camber, king pin inclination and scrub radius, not something that you can do with a "donor" upright. Usually you need to start by working around the chosen upright's limitations!

I'd like to do the designing myself now but I'm just too busy at the moment, soon though

Cheers
