Catch can and pipe blocking bits........

Fitted my new catch can that i bought at the weekend, just want to check what do people use to block the pipes that are left over from the intake manifold and the induction pipe. Pictures included.

Ive seen these kind of rubber bungs that you can put on the ends of pipes, anyone know where to get some?? Ive found a picture of the kind of thing im looking for and the pipe that i need to block from the intake manifold is there too:

Just put a rubber pipe off that the size of a bolt and put in a bolt!!:)

Ive done that on one side (if you looked at the pics EOIN!!) ;) just trying to see if i can get the right bits for the sake of it.
