Looking for Part for Ferm FZT250?

I'm looking for the black plastic guard that goes around the blade to funnel the dust to the extraction port. I tried to make some modifications to mine and ended up breaking it. It doesn't look like this a part that you can buy so I was wondering if anyone has a broken saw that they'd be willing to sell the that bit from? Unless anyone knows somewhere that does sell them? Thanks
