I have now redone the rollcage in 4x1mm brass tubing. I didn't like the plastic version. There's also magnets holding the bonnet and roof down. Lightbar is on the roof but no led's yet. I need to tinker with their wires to make it look more tidy.
Steering will be redone with smaller diameter cables once I get the new parts. Now this thing waits for warmer weather to start painting.
