Where does the rack sit in relation to the engine? If it's below the sump can that be modified to lift the rack so the steering track rods go over the wishbone?
Thanks for sharing. Lots of pages... Anything in particular you want me to look at?from the forums

I've been building and racing various oval cars over the years and I've tried to pack in numerous times, but I can't:ashamed: This is a car I built about a year ago, but it has had some not so nice mods. To a slight improvement. and in shale guise.www.mig-welding.co.uk

Here you go, it's a on shed based on beetle parts but it keeps us entertained:www.mig-welding.co.uk
It has been considered, but that would mean the wheels would no longer be centred, along with other issues.Swap wishbones left to right? I know that won't work just like that but new wishbone mounts may be the better/easier option than modifying/making a wishbone with a hump in it. Even if you have to make a new or modify the existing wishbone to do it at least it will be easier to do well.
I am sure that your not allowed to repair pre made high stressed sections like wishbones.Yes.
The MOT manual isn't great and in the eyes of the DVSA the tester is always at fault,I am sure that your not allowed to repair pre made high stressed sections like wishbones.
For road use anyway.

I've made a jig as is evident in the first pic. If you start the thread from the beginning, I stated that this is a proof of concept and a revised version will be made in due course, preferably out of tube. I don't have the tools to bend tube, so I'll have to make do with what I have for now.If it were me, and for off road use only, I'd not use sheet steel. At all.
I'd get a spare arm, and make a jig that it bolts to, so you know it's square.
I'd cut the mounts off the spare arm, discard the rest.
I'd make up the arm from thick wall tube, bent and gusseted appropriately, welded to the mounts.
This is a MacPherson strut, so it's the shock and top mount that will take the load at the top.Can't see your original picture, but suspension arms resist a lot of forces, sometimes in direction you never thought of.
So you think it needs to resist lateral loading from cornering, or smacking into a kerb. Rearwards from braking, or bumps.
Ever considered what happens when you brake? Caliper trys to stop the disv rotating - in effect, the disc trys to drag the caliper around the wheel centre - so the suspension is also trying to resist a twisting force.
Common, and to most, a surprising failure on double wishbone systems is an under-specced top rose joint bending forwards due to that braking reaction force.
Could you instead find a track rod, or track rod end that has a suitable shape to clear what you need to?
Be very careful of bump and roll steer effects if you've moved the angle of dangle simply to get an engine in.
I like the above idea of making a jig around a known good arm to either make or modifiy an arm.
The track rod isn't parallel to the rack, so the tube would need to be oversize to allow extra clearance on the ID for the track rod to go through at an angle. Also keep in mind that the angle changes as the steering moves.That lower wishbone could be cut to let in a tube for the the track control arm to pass through, bracing could be added to the tube.

The track rod isn't parallel to the rack, so the tube would need to be oversize to allow extra clearance on the ID for the track rod to go through at an angle. Also keep in mind that the angle changes as the steering moves.
The rack boots are around 70mm OD, so the tube would need to be considerably larger. Not easy to find a short section with a 2-3mm wall.
The other issue I have is that there is also a restriction on how much room I have to work with, else I will need to clearance the chassis to allow the modified wishbone to pivot unhindered. What I have designed is optimal and fits within the space available.
