I can give you a description?
-remove your forks and bars from the headtube.
-take a screw driver to the inside lip of the cup, and hammer around the perimmiter, until it pops out.
-repeat step for the other cup.
-Allign the new headset cup with the headtube hole, and gently hammer it with no covering of the headset to get a lead.
-Then, use something to seperate the headset and the hammer (I like to use a notebook/journal) and just start wailing at it.
-repeat for other side.
