I have the gas tank out of my 1987 Cutlass and was wondering which ends of the straps need to be installed first on the car I have the rear staps installed but when I go to put the tank up the fronts of the straps will not reach the holes in the body where the bolts go through can anyone tell me what the problem is or do I install the front straps first(the ones near the rear bumper or what)?THANKS
