Have made another step forward this evening after work as now I have lowered the rear body onto the chassis
Took it outside for a spin in the yard probably the first time the chevs moved under its own steam in years.
Note - this is what a happy rivet looks like
Now to sort out the steps, wiring loom, front shell, wings etc etc can anyone tell me the system used to hold rear body to chassis rail.
Heres a better shot without a rivet in the way

very nice to be able to dive the beast at last can't wait to start using properly
