850 sunroof problem

[drew5535]

I was having a problem with my sunroof on my 93 850. It would not open or go up to the vent position, but I could hear the motor working. So I took off the sunroof and realized that a part of the plastic guide on the right side was broken. My question is am I able to buy a new plastic track, if so how much is it and where can I get one from?

Thanks
