Ever since I bought my FJ40 in 1990, I have been annoyed at the rear sill area collecting crud. After 35 years
, it was time to do something about it. I also live on a short dirt road, which makes constant dirt a problem.
I installed mud flaps way back when, and decided to now mount an 'upper' mud flap that would protect the sill area from flying mud. I had a stiff pair of 12" wide by 18" tall flaps, and cut them down to 13.5" and mounted them to my existing mud flap bar. See photos.
If I didn't have period-correct cool mud flaps, I would just buy a 24" tall mud flap on eBay, cut it half, and then make it extend from the inner fender top all the way down where a regular mud flap goes. The new flap is held in place by the fender support and sort-of jammed into the sides of the fender. I greased the heck out of the sill area (now hidden behind the flap).
The first photo shows the newly cut 'upper flap', the 2nd one shows it installed (inside the rear fender area) and the last one shows my regular old flap. The flaps are mounted on a piece of modified angle iron bolted to the taillight housing hole and the very edge of the fender.
