All of the above is great information and right on the mark. It would have been very difficult for me to do it without the leveler.
The only other suggestions I would make would be to use a digital camera and take lots of photographs. I took a photo nearly everytime I took something off. I know it sounds a little crazy but when it came time to put everything back together there was no uncertainty. Especially if there will be some elapsed time between the removal and the replacement.
Also, I used a box of zip lock bags and labeled every set of bolts etc. that I took off. For the first time ever, I didn't have bolts left over in the coffee can or short bolts when I was done.
Wish you guys good luck and come back soon.
