I have an '88 that needs a new headset and what I thought would be a relatively painless process with my LBS turned out to be quite the opposite, now I'm out in the cold and need a little guidance. The headset is Shimano 600EX, like this 105 except all silver.


I've done some searching and found the following. Would either of these work?

Does anyone have any other suggestions?
