For the passenger side (which is in rougher shape than the driver side), I picked up a full floorpan (57" long, I believe) from Sherman Auto Parts
today. It looks like the one in the photo below (passenger side only). Bonus...the company is based out of Washington, Michigan, so we're supporting another Michigan business with Mira's Cherokee build.
I also found this "paint inspiration" photo while surfing over my lunch hour. It's very similar to the look we'll probably be going for.
