i took my 05 gt to the dealership for the gas tank tsb. they said it would be a half day thing. the tsb says 1.9 hours. i dropped it off at 7 a.m. and told them i would like to pick it up at lunch time, i was going out of town. at one oclock (6 hours later) i called to check up on it. they told me the tech has never done a gas tank on an 05, so he would not give an exact time when he would be done. they said that he has to remove the drive shaft and the exhaust to remove the tank. he was removing the drive shaft as i called. they told me it would be several hours before it would be done. if it pays 1.9 hours to replace the tank, is it necessary to remove the extras? i am a body tech and realize that sometimes things take longer than they pay, but this sounds excessive. what does the service manual say? the service manager said 1/2 day to do it.
