6 , As of now I am going to depend on not getting a flat(fingers crossed). Under the bed area in front of rear end is already full of exhaust system and mufflers. This is one of the problems of modifications. This truck came already hacked up beyond going stock short of a ton of money to get back to stock. I am trying to keep the outside as stock looking as possible and that has not been easy to get back to. My truck is not going to be as nice as yours, however trying to make a dependable driver out of it. Ed
