Your build sheet MIGHT be above the gas tank. It MIGHT also be tucked into a seat spring, up under the dash, behind a door panel or even somewhere else. If it is above the gas tank you may or may not see it. I sincerely hope you find it but don't count on it. They're usually long gone by now. If you do find it it is very useful because it lists every option on the car and other info. Good Luck. Keep us posted.
