Added a few more gussets and floor diagonals under the engine. Removed everything from the chassis so it can be rolled on its side or back. The chassis isn’t complete; the idea is to finish everything near the floor that’s been tacked-welded. The idea is to fully-weld everything so panels can be attached without concern about heat-distortion shifting the rivet holes.
There’s still lots of tabs and brackets to weld on for the seats, fuel tank, coolant tanks, seat belts, etc. However, they don’t require pumping a lot of heat into major tubes and can be done later if desired.
