What is the best way to go about finding missing files for truck that need them? I have the SM4 (.38 compatiable pack) and a bunch of other trucks. The .38 pack runs fine, but all the other trucks are missing several files (GreyHydrolic.mesh, PEI------.mesh, etc). Is there a way to easily find these missing files or is it all trial and error as far as downloading randomm trucks?
