Power window blues...

Hi everyone!

During the blizzard I was trying to lower the left rear window on my 94 S500 (not smart - it was frozen)... Because it was frozen hard, a loud BANG came out of the door. After that the glass pretty much fell down into the door and now isn't suspended by anything, moves freely up and down by hand. I understand that it is the regulator, but may be somebody can tell me what I am looking at before I take the door apart. Could it be something that a machine shop could make? Don't want to replace the whole regulator assembly if it is only a linkage of some sort that broke...

Thanks!
