"Smaller" floor pan panels

[Jemezcrusher]

Had the cab of my truck blasted yesterday. Had some active rust in the floors where the floor board meets the toe board. I have only found full halves so far. I really only need 6" either side at the worst and hate to either replace the whole halves (huh?) or cut up new pieces and fit them in the 1.5 square foot areas I need to replace.

Anyone found alternatives? I could piece something together but would like to keep the original look of the rib/reliefs
