Front Suspension Wishbone Arms

[4129R]

now this "switching around" of the top wishbone arms, may it possibly be intentional???   what benefit might this mixed up configuration provide?  Perhaps more nimble steering?   perhaps allowing more room to adjust toe-in/toe-out?
just thinking outside the box here and thinking owners may have found a secret they're aren't sharing???   What betterment or detriment will result?

As far as I can work out, swapping the wishbones back to front only affects the castor.

Toe in and toe out are adjusted by the track rod ends only.

The trunnion has no flexibility for "sideways" movement.  You can't adjust castor.  Fitting the upper a-arms incorrectly will result in considerable stress to the trunnion and a-arm bushings.  If you are lucky, the only problem will be excessive wear and a short service life.
