guides

Is there something in particular I should be looking for in a timing chain kit for a 3.5? My main concern is the quality of the guides - don't want to be back in the P0017 club for a while.

I'm getting really annoyed with this damn driver door window lately. Everytime I roll the window up or down the rubber guides on either side of the window squeak and stick to the window causing it to stutter and roll up hard. I've tried everything to get it to stop but no luck. Is anyone else...
