The upper guide bushing that came out with the seal has its coating on the inside. If it looks worn, give it the same treatment. In fact, because of the banging it gets on its way out, most manufacturers recommend replacing it with the seals, and so do we. Assuming everything is in order, it's time to re-assemble the fork. There should be an exploded view of all the parts of the fork in the factory service manual that you have open in front of you.
Installation is the reverse of the disassembly, with the exception of banging the seals back in.
With the damper rod installed and tightened, slide the upper guide bushing over the fork leg and into the recess where it sits in the outer leg. With a little luck, they just may be the perfect size to use for a make-shift seal driver. Just make sure that the bearing race doesn't get jammed in the same housing the bushing is going into. If it looks like it's going to work, use a heavy hammer and a flat-blade screwdriver on the bearing race to gently drive the bushing in. Make sure to start the bushing carefully, tapping around the circumference of the driver, so that it goes in square.
