ok i've heard everyone saying that they drag their gas tank on the nbs so they gotta raise it or put a drag plate under it. now i have a 97 ext. cab thats on a 4/8 drop and yesterday i noticed that it sounded like i was draggin something while i was going over some small humps in the road. it definately didnt sound like metal on the ground but it sounded like plastic or something so thats why im thinking its my gas tank. any help would be great.
