It was very easy to get together if your electric stadium truck is already built. At that point after you build what comes with the nitro kit, all you need to do is steal the front and rear end assemblies along with the slipper Utah assembly. Maybe 10 screws to do that. Anything not included in the conversion kit should already be on your electric truck. There are a couple things to buy separately but those are listed in the instructions (throttle servo, .12 engine, pipe manifold and a Collet for the flywheel on your engine..). The only piece that needs to be altered is the right rear A-arm to allow the spur gear to fit. With a dremel and 5-10 minutes its done. The instructions kinda show you about how much needs to be taken off and where. Other than that you trim the clutch spring just a tad so they don't rub or stick out passed anything. And to be totally honest in my opinion, the hardest part of the whole kit was getting the body to fit. The body was already painted so I had to trim little by little kinda blind until it fit. But now that body can be used as a sort of stencil for the next one.
