Shadow was the guy that tweak the menu car icon files for the community mod.
I took a look at my unpacked FO2 and in the \data\menu
folder I see car_icons.dds
files. I believe these the files that have the icon pics. My photoshot won't load these files now, don't have the plugin to load dds files.
Will need to paste in a small pic of the van into the right spot of the car icon menu pic file.
