i may not know enough of how to speak to metal myself but i definitely know what gadget would do the job correctly and have past experience to put the right gadgets to use
beside other tiny metal shaping gadgets, for floors, i have bead roller, pneumatic planishing hammer and shrinker/stretcher (will also be used for windscreen channels). also have english wheel to do the complex curves and panels
lets wait until its time to put them all to work and we'll see 
all i needed were correct profiles and i had help from an english friend who had a NOS sill/rocker panel to stencil out the profiler

front floors on my pella were replaced by patch work so i needed front floor profiles, its where an aussie friend came to help. with correct gadgets, these are now a walk in the park 


if you are picky abt the under the throttle pedal curves, i have the profiles on my pella and this is where pneumatic planishing hammer comes to rescue to produce these perfect curves
