Getting ready to do some floor rust repair sections.I am concerned that if I cut out one half of the floor at one time & do a half floor pan replacement that the body could flex/move around & ruin my perfect body lines & gaps.My rust areas are not that big & am leaning toward just cutting sections out one at a time.I did get the one piece seat base & the conv. underside sheetmetal for my 66 coupe.Looking forward to your input. Thanks, tom south florida.
