A friend car is here in my carport which I trying to cut out rusted out sheet metal and weld in new fresh sheetmetal.

We already knew that the floor in driver and passenger are rusted out and patched more than one time.

I wondering about to cut out everything between doorsills (spelling?) and weld in thin rectangular profiles then rivet in aluminum plates that acts as floor?, maybe cut out the cardan tunnel (spelling?) and weld in new and higher mounting base for shifter.

Anyone who did that before and is it legal?

The car will be a road and track car with full cage.
