Ok, Just wanted to ask you guys one last question.. I'm having the installation of my Pro 5.0 3.90 gears done by someone I know.. well.. what all do I need to give this person... he works at a Mechanic shop and that's where it's being done.. should he only need the gears? (Ring & Pinion) And everything else should be a stock swap? I don't know if the Pro 5.0's come with Shims or anything like that but then again I tried to search for these and couldn't find anything.. Thanks a lot.
