Do I detect the sound of an opening can of worms?? 
This has been discussed at length on here. The best thing is to do a few searches.
There are several solutions to the front wishbone situation. It depends on the type of wishbones / angle of the 'L' assembly / positioning
of the FUs and the type of uprights used, (to name but a few).
A bit more info about your build would be helpful.
Cheers Mick

What's your concern?
Is it that the top brackets are hanging off the chassis a long way? You could put a web at the back of them to the chassis rail to reinforce them.
yours, Pete
I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.

bracket positions
yep front top wishbone bracket is hanging
off chassis more than i would like to get five and a half degree castor angle.
Also do top and bottom wishbones have to be parallel with each other when bolted to the upright.
I am useing GTS brackets , wishbones and cortina uprights
cheers

As Pete says, gusseting the chassis at the bracket attachment is probably the easiest solution. As for the bones being parallel, it depends what you
mean. The pivot axis' at the brackets should be parallel, the wishbones themselves should diverge, ie be closer together at the chassis than the
upright.

Pwalt,
I used the following plans for mine:

Seemed to work ok.
I did find that the bracket supports 'pulled' the brackets out of alignment slightly so watch out for this.
When putting the brackets on I'd highly recommend making a jig like this:

Use the rear, lower brackets as your datum point- as they will stay in place because they'll 'sit' on the chassis.
HTH,
James

Hi,
I think you will find that the wishbones SHOULD be closer together at the chassis than at the upright. To put this another way, if the lower wishbone
is parallel to the ground then the upper wishbone should slope away from the upright. This is good because it gives you negative dynamic camber. This
means that as the suspension compresses under cornering (ie. Cornering load), the wheel will gain negative camber which generally is a good thing
unless taken to extreme.
I will try to find a photo of my car from the front to show what I mean.
Here's one from June '03:
Cheers,
Craig.
