Real lower doors are expensive...Here's my solution!
When I bought the FJ40, it had these custom rear half doors. They looked fine but weren't functional.
After pulling the carpet and custom doors, there was a ton of rust on the rear sill. What didn't fall off, was easily removed with a cut-off disk. Since I never opened them in the two years I drove this as a daily driver, I decided to close it up permanently.
The new panel was cut out of 14 gauge. I used square tubes to continue the factory top rail of the tub, another at the height of the top of the wheel wells (inside) and a third tube to replace the rear sill.
After patching all the panels I finished out the corners of the rear sill tub support with 1/8 plate bent to form a tube that follows the bottom of the tub.
