You will want to have an impact wrench and an allen driver for the damper rod bolt. I can't remember if it is an 8 or 10MM allen. I made a long one by cutting down one of my kajillion "L" wrenches, and just put it in the appropriate socket. Seal driver to put the seal into place. I make mine with a piece of pvc
that barely fits over the fork tube. You can use a long piece that comes over the top of the tube, and push it that way, or use a smaller piece and make a 2 X 4 push board to drive the PVC and the seal. You need to make sure you feel the seal pop down into place, or it will leak.
For measuring the fork oil height, I use a wire coat hanger. You can put a "flag" of tape at the height you want. Remember to remove the tubes and drain them well. Pump them up and down several times to help evacuate the bottom of the tube. Some folks put a little ATF in the tube after the fluid is drained, and use it as a flushing agent to clean the bottom out prior to removing the damping rod and piston. When going back together, put about half the fluid in each tube and pump them 3-4 inches several times until you don't feel any air going thru the bottom end. I usually let them stand like that for about 5 minutes and repeat prior to topping out to measured height on the oil.
Hope it goes well.
