Trouble Installing Addons

[crazyhotrod1555]

I tried to install the 5 spoke wheel and rollbar for the 1990 k3500 but then this happened. Is there any small errors I could've made editing the truck file to cause this?

A lot could have gone wrong. In the game, you can press ~ to open console window which shows errors and warnings from the spawn process. You can also look into RoR.log which has even some more details.
