Is there any way to tighten this piece down or make it a little quieter? My knee rubs against it and it sounds like an old screen door.

 

It's held in place by plastic clips. If it's been removed multiple times, replacing it (the clips are molded if I remember correctly) might tighten it up some.

Got it - was able to put a little white lithium grease in the clips and I think it helped a little.

The passenger side one is a little messed up, so Im going to order a replacement. Any one have a clue what color this is? There is:
OBSIDIAN METALLIC
ARMOUR SILVER
DARKSTORM METALLIC

The part number I pulled off of the part is FL3B-1822642-C however Tasca doesn't seem to have that part, the numbers seem to have changed...

The number stamped on the parts is just the engineering number (or internal number or something). Part numbers for ordering are different.

As for the colours Obsidian metallic I believe is for Lariat, Armor Silver is XLT (verified - I had to replace one of mine), Darkstorm Metallic - Platinum?, Dark Anodized - Special editions and Limited?.

Don't need to get the whole part though if you are just after the clips - part number W714972-S300.

 

You could also put some foam tape on the inside where it comes in contact with the door so it will keep tension on the piece.
