how do you get the external window washer sprayer thing off a 70 kombi?

can you take them off, where from
also, how about the rubber molding on the back of the front seats, they have those rivet looking things, should you take these off as well, and is it hard to put back on, i am changing interior/exterior colours

You have to get to the back of the washer nozzle and squeeze it gentle with a set of pliers and push it out.
