Sunroof won't close!!

[polarisrmk]

So i have been searching the forums for the past two days about various sunroof issues and haven't found anyone that has the same issue i am having. For starters it is a 1985 300SD. The sunroof opporates flawlessly until it gets to the point where it is supposed to be pushed up to match with the roof panel and it just stops. It is closed all the way but just never matches up flush with the roof panel on the outside. If i hold the button and help it it will go up but i am affraid i am going to break something so i don't do this. Does anyone have any clue how to fix this. I thought about getting the sunroof repair kit from kent on MS but I have heard bad stories about him.
