Sounds easy enough, I just remember when I started a Locost back in 2004 that this was one of the difficult bits to get done ( or there was no information ). Which is why I bought Astra bottom ball joints.
I gave up that build due to a number of issues and sold the chassi.. I got an email last year from the guy that bougt the bits saying he needed a quick letter to state the chassis was new as he was about to register the car
