Five years ago I stayed up all night dismantling the Texas truck. One year to the day I stayed up all nite again to finish putting the rear end together, and then decided to put it back under the truck. I got all the tires mounted and aired up too. I need to cut down the new brake pins and really start to tighten all the chassis loose ends, grease certs, and drive line. I had a moment of panic while in the middle of putting the rear end in, I looked at the motor mounts and realized when I reinstalled them I did not mark which was right and which was left. I racked my brain for a hour or so until I remembered I had a extra hogs head(fly wheel housing) on the shelf. Crisis averted engine mounts are proper.
