I had to fabricate a heat shield because mine on my JKU was missing. I had to replace the starter because of heat damage, it is about ¾” from a catalytic converter.
This is the heat barrier which has adhesive on the back and what I used to protect the metal I used for the heat shield.
This is an aluminum chimney vent cover, I salvaged the metal from this to make the heat shield. Use what you have available or acquire some light sheet metal or aluminum
I clipped the grating off and used a piece of cardboard to get a rough design to apply to the aluminum so I only had to cut once for the large shape and then made small adjustments until I got it into the correct shape for my application
Here are the measurements if you wanted to create your own. Take my measurements and make a cardboard pattern first and then adjust to your application.

Here is another view of the final product
This is the shield with the heat barrier attached to the metal shield
The starter unprotected. The hole directly under the starter worked perfect as the second mounting point for the shield.
Heat shielding complete and installed.
I added a washer and locking nut to the original starter mounting bolt as a heat shield hold down point
Heat shielding complete and installed, showing the air gap between the shield and the catalytic converter
Complete and operationally protected from heat.
