Are there any known rust repair panels (floor, eng compt, Qtr inner...) that can be retrofit to the Maverick. I'm not asking for plug and play, but is there is a certain year Mustang floor panel, for instance, that requires less work then others? I'd rather start with a good stamping (including stiffening beads) then try to work flat sheet. Please reply if you have personal experience that may be helpful. Thanks!
