I have a Cutlass S that needs a trunk pan, gas tank, trunk & gas tank brackets installed. Just curious what that would cost me? I already bought the tank, trunk brackets ( that go on top of frame) and the brackets that weld to the bottom of the trunk pan for the gas tank straps to hook into. If I bring this to a body shop what should I expect in pricing? There are about 5 different pieces that need to be fabricated also because the floor I bought does not cover all the way. Any insight is appreciated. Thanks.
