you have to get an inch pound 1/4 drive to do it exact, multiply 8.7 x 12. I put a 4 inch extension on my 1/4 inch dive ratchet and hold it so the head of the ratchet is in the center of my palm and snug it that way. it limits the torque you can apply and gives you a good feel. I usually find the factory specs on those small bolts uncomfortably tight. I use blue Loctite, tighten them just past snug and make sure they all have even pressure. use a criss cross pattern like lug nuts and do it in stages. I usually do 3 times around. I have had much better luck being leak free with this method than just using factory speck. just be careful and take your time, don't use more energy that it took to loosen them.
