Thanks for your advice. I think I know how to do this now, based on this and other threads and I just might give it a try...
I have one question, and it may be a dumb one...
I realize I should measure carefully and cut only once. But what is the right height? Should I just replace the washers that are on my stem and call it the day? Can I heighten it somewhat (limeted of course by the toal stem length)? How would I go about that?
Can I test ride it, meaning installing the washers and stem and ride it for a few days and then adjust it before swaing it to the correct length? Or would that be a dangerous thing to do? Is the topcap required to ride safely?

Thanks, Duppie
