Dodge 1995 Ram Van 350 Window Question?

Hi,
Tried to search, but no luck. My father in laws driver side window fell apart. He has a long u shaped galvanized rail that came out(don't know how). He wants me to help put it back together.

Is there a diagram somewhere or directions? Any help would be aprreciated.

Thanks,
Scott

Why not just pull the panel off the passenger side and look at that one, it should be a mirror image. Better than a web picture if you ask me.
