Hey Miz,There Should be a Small Plate About 1 Inch Long And About 1/8-1/4 Inches Wide on The Driver side at The bottom Of The Windshield Right Where The Dash Butts Up Against The Windshield,Then if That Fails,Look On The Inside of The Driver's Door Either on The Jamb Where the Latch that Holds The Door Closed is Mounted OR On The Door,Usually You'll See Stuff On There Like It's A Good Idea to Use Tires On Your Car For good Ride Quality( i Personally Prefer ROUND Tires)

,The maximum amount of Weight To PutMoochersCar(Helps Cut Down On Ride Moocher's) Where Your Car Was Made,Etc,Then if No Luck,Try Inside the Glove Box,The Numbere's Wherever you Find Them Will Be aboult 10-15 digit's long With Letter's here And There.
Good Luck.
