I have custom bash plates made by Macquarie 4x4.
I didn't get them made but was lucky enough to pick them up for a song when a forum member sold his WH a few years back.
Transmission guard, I have never used it.
Front, well used
When both are on there is a totally flat surface under the engine and transmission.
Note, these were designed to fit with a factory bumper so the front edge doesn't line up with my bar.
Here is there contact details
