Where are all the parts to Monster McQueen?

Okay, once you've gotten the task from Luigi to go find the three parts for McQueen, you need to find a horn, some tires, and some shocks. They're all to the west of Luigi's and pretty easy to find. The horn is right on the main street just past Luigi's, the tires are behind the fire station, and the shocks are along the dirt road behind the big butte behind the fire station. Cheers!
