Some parts stores actually carry the clamps. You are supposed to use a special tool to squeeze the clamp shut, it pushes down on the center while you squeeze the sides. If I put the original back on I'll just use a hose clamp that can be bought anywhere. It does the same thing it's just not as fancy looking and is removable. A lot of CV boots use those style clamps so people don't mess with them.
Glad to see that everything else went well.
Do you have a dual valve catch can, and if so how did you hook it up to the "T" valve with the hose sizes being different? I'm trying to find a nice plain and clean way to do it.
