This simple mod removes the need to customise the cars you steal for the Chop Shop Activities, similar to how it works in Saints Row 2. This won't be compatible with any mods that edit lc_chop01.xtbl, vk_chop01.xtbl or wr_chop01.xtbl, but it'll be compatible with any other mods!
To install this mod, unzip the mod's zip file, copy the .xtbl files into your unpacked misc and misc2 folders, and then repack the misc and misc2 folders. I haven't personally used PhantasyRow, so I can't help with installation if you want to do it that way!
