Opel Chassis Issues
John, I have had those same issues with a couple of Group C chassis. I don’t know why its a problem on some and not others. I have an Open and there is not a lot of material on the front axle chassis loop. Good luck with it. Chassis are readily available. I even saw a guy on eBay selling a complete chassis less body for $27. Not a bad deal for the full set up. Could be a good test car chassis.
