Thanx for the comments much appreciated to know that I'm going in the right direction with my models.
Nicolma, the mechanics and tools are the Tamiya rally mechanics set (1/24) straight out of the box.
I was thinking of adding an air hose to the wheel fitter but had nowhere for it to attach at the other end, Might have to scratch build the air compressor though.
I will post a couple of pictures later in the week.
