Newbie needs help...

[EZY]

I'm the new guy at both this forum and Boxster ownership so here goes. I bought a 2002 Boxster S just because I saw it sitting on this car lot as I was driving by..it was love at 1st sight. First I put a new top on it n learned all about those clogged drain hoses n how to clean them..my question is about that piece of canvas attached behind the seats with the water channel clipped so that water drains into the two drip pans n down the drain hoses..since mine is dry rotted n has holes in it I need to either replace it or repair it..what is it called n how do I get another one..or is there a way to repair it? Somebody help..PLEASE!!! Thx in advance as I have no idea what to do...I'm loving the forum n have learned so much from it already...thx for all the help.
