Looks right to me, mine are oriented the same way.
You couldn't pwn your way out of a wet paper bag, with "PWN ME!!" written on it, from the "pwned take-away" which originally contained one
portion of chicken tikka pwnsala and the obligatory free pwnpadom.

Looks ok to me too.
If you look down from above the top ball joint should be behind the bottom ball joint. (imagine dangling a plumb line)
This helps give it some self centering.
Cheers

Thanks guys, longest side to front is what I thought.
And it self centres 
Without valve springs in the rack and without 23 degrees of toe in, just lots of chalk lines on the garage floor and a geometry set

does it self centre properly dude when you drive it not on the spot

It self centres when I sit in it in the garage and go brmmm brmmm.
It certainly doesn't fly back but does come back to rough centre at wet, greasy public road speeds as tested today.

I've got 6 land rover valve springs at the ready in case it didn't work!
Still not 100% as the camber looks a bit excessive to be honest.

does anyone know the engineering reason to make the bars oval rather than round?

Not pretty? Is that because the GTS ones were triangulated rather than the "pre-failed" curved design? Give me engineering purity over
aesthetics anyday.

The reason I asked is because the oval bar would have a worse neutral axis and you would also loose the all angular strength of the round bar which
would therefore make the oval bar the poorer option because it would have to be heavier to have the same capabilities of round. Anyone out there with
a engineering degree could show a proof for the reason to chose oval? I've always been told by my father (civil engineer for 30 sumthing years)
that round bars have best structural strength but were used less because there difficult to work

I think the reason for using oval is 99% aesthetic, though the failures of the lower wishbones often discussed on here tend to show the rearmost part
of the wishbone failing by bending towards the back of the car (i.e. failure likely occured under braking) so an oval tube of simmilar weight to round
would be stronger in this axis.

Think u r spot on mike, u wouldnt build a chassis full of bend would u ? The first time I saw that top wishbone I was glad it wasnt on my car
