Do i have enough length!!! :D
On the front of my Luego i have cortina uprights with the classis maxi balljoints and transit draglink tops m18 iirc. But i have massive camber and if
i unscrew them im worried there will not be enough threads in the arm... here's a pic of the camber and where the thread goes to at the moment
(to my finger nail)

Why not unscrew it until you have about 1mm of camber and then check how much you have in there. Then make a judgement?

Lock nuts were normally supplied with the arms. Failing that a good nut & bolt stockist would have them.
Beware of the Goldfish in the tulip mines. The ONLY defence against them is smoking peanut butter sandwiches.

Are you sure the wishbones are suitable for Cortina uprights?
They might be designed for Sierra uprights?

Yeah classic. I had it the other way. Cortina bones and Sierra upright. It looks like you have Sierra width bones and Cortina upright.

My Luego Locost uses Cortina uprights . IIRC Lolocost sell the lock nuts. If the end of the thread is level with your thumb in the second piccie I
would have thought you have enough thread to adjust safely . Adjust it and recheck!

Its a Luego Velocity with Locost GRP and i did spec Cortina Uprights when ordering... i hope they got it right  There exactly the same length as
the rears if that makes a difference. It just looks like there will only be an inch left in the arm if i wind it out which i would have thought would
be unsafe with heavy breaking. hmmmmmmmmmm now im worried. lol

Thread Engagement
A safe minimum of thread engagement would be 1.25x the thread diameter. This would be 1.25x18 = 22.5mm.

That's the rule of thumb for a bolt used for clamping, but in this instance the further the balljoint is wound out the higher the bending moment
being applied to the rather stressed section of thread between the threaded tube and locknut. I'd certainly want the TRE screwed in as far as
possible.
