Sunroof track

The arms that lift the sunroof up to vent or seal broke on my truck. Does anyone know if it is possible to just replace them or will i have to replace the entire track since it is riveted together.

I just had a complete failure on my sunroof. I went to open it 3 weeks ago and heard a loud pop. scared the shit out of me. Barely closed the sunroof, it would go sideways and was PIA to get it to align and get closed. Took it to ford two weeks later and end result new track at the tune of $1769, list price for a new track is around $1200 has to be ordered in plus labor ....Fortunately my extended warranty covered it all. Just deductible of $100.
