Hi there,
I was lucky enough to get one of the prototypes and having read the manual that Chaz wrote all I can say is read it - it has most of the tips you need to know about building the car in it already
. The only thing I would say is on the rear inner hingepin brace don't fully tighten the screws until the hinge pin bushes are located otherwise might not get them in.
Enjoy the build, any questions just ask!
