Any one have a comment or experience with these on 1st gen VRs?

The next link has more parts shown on the bottom of the page. Some come with the slide others are just the rubber, spring and o ring. Can the slide be easily connected to the diaphragm or is this a tricky think to do. What do I need and how do I make that determination?
