Is this correct?
Discussion
It is common nowadays to have no washer in such applications, but personally I consider it bad engineering practice. I always prefer to use a washer between the nut and the component as it enables better control over the torque values when tightening and also spreads the loads over a larger area, reducing stresses.
Also there should always be a minimum of 1.5 threads protruding through the nut.
Nylocs should be used once only. Safety!

As said, washers not usually fitted by manufacturers but will do no harm if enough spare thread, which is M10 fine.
Track rod end locknuts are M14 x 2mm pitch from memory?
One school of thought says a washer spreads the load better and should be fitted.
The other school of thought says that a washer reduces the number of threads proud of the nut, and in the real world, isn't really required on something like a track rod end.
Only thing I'd say that needs to enter the thought process when debating whether to fit one or not, is to make sure the taper of the joint isn't meeting the nut. Because these cars were thrown together using all manner of different components, sometimes washers were vital, as the taper of the chosen swivel joint is too long for the bore in the upright or whatever it's fitted to. That means your nut tightens up (or won't tighten up) yet the taper isn't seated fully.

...Same track rod end going back into same steering arm? should be ok
Also a good point. But it is a TVR! and who's to say it's the original track rod end? I still won't be surprised if the other side is metric and on the other hand....it might be the other hand. if you see what i mean.
I was told as a lad that metric threads were averaged and rounded versions of whitworth. i believed this because i am not french. is this correct? (except 13mm, which was a further cock-up to put us whitworth boys off.
oh and the thread angles were all wrong too. Mutter 'Foreigners'
I wouldn't be surprised if it was an Acme thread!
