Thanks Deb! It was actually much simpler than I expected. I did check the Park Tools site, then realized that I didn't have nearly as much to do as they indicated on their headset page. The headset was all in, so all we had to do was grease the fork steerer tube, slide it up through the headset, put on what I guess is the race, then the spacers, then the stem. It seemed really easy. However, since I am going to the LBS tomorrow to have the bike serviced, I'll have them check it. The fork may have to come off again anyway for servicing, but I mostly wanted to get it on for the time being so I could roll the bike in the shop (and check the standover, which is just fine).

Thanks so much for taking the time to post. There were no replies when I got started on the job, so we were forced to figure it out on our own (hubby and I), and we did just fine (I think!!)
