Gus cuda, The Soffseal convertible weatherstripping kit does not come with the window felt. Also, it doesn't come with the A-pillar weatherstripping either, that has to bought separately as well. What the kit does come with is 7 pieces . Three different length pieces for each side that fit into the channels and one long one for the front of the top (where it meets the stainless steel).
I'd also recommend that when you change them out you do them one at a time. That way you can be sure you get the correct length one in the correct channel and in the correct position.
Someone once told me that Soffseal does not sell to individuals, you have to buy their product from one of their distributers. Maybe that's not the case now - who knows.
