UPDATE: New to the Peterbilt 389 - Drop Legacy Sleeper!!
Truck version 1.43 includes a new drop-down sleeper option as well as new chicken lights along the rear edge
of the sleeper. This update will also provide provisions for a new grill insert that will allow you to put a custom image
in the grill area. This option will require the open def grill insert mod.
This mod will allow you to insert your custom image or logo.
If you have any questions or issues, please respond to this post or place your concerns on the discord message board.

This mod is an open def mod that will allow you to insert a custom image into the grill area of your Peterbilt truck.
There are two grill insert options to choose from. You will need to open the packed mod to access the template and the decal sheet.
Use the template to create your custom image or logo and replace the dds file with your new image.
Do not modify the name or the mod will not work.
That's all there is to it! If you need any help, please stop by the discord message board.
Thank you all for your support! I really appreciate it!
NOTE: This mod will require the Peterbilt 389 legacy truck to work.
