window reg idea?

Well, after trying all the window fix idea's i could find on here, none have worked. I've noticed that the plastic guides on the track have a bunch of hairline cracks, and that's were all the flexing is. I'd like to just replace the whole thing. I've found a window regulator from isuzu parts online, but it doesn't have a picture or description. so, does any one know what I'll be getting? is it the full assembly or just the metal track..??

I don't know if this is same case, but I had similar problem with the window regulator.
I used WD40, but it made the thing worse.
Then I used silicon lubricator spray, and it made everything normal.
I would try it before replacing whole system.

If this is not your case, just ignore when I said.
