Quality of this Fairchild Industries weatherstrip is very good. Much better then the OEM that was originally on the truck. My truck is a 2005 GMC Sierra 1500 SLE Extended Cab.
The on-line information said this weatherstrip was only for the passenger side but it also fits the driver side. The other part number listed for the driver side (G3085) did not fit but the (G3087) part fits perfectly for the driver side.
When you install this weatherstrip, you will find that it is a few inches long. Do not cut off the extra, just butt the 2 ends together and push down the ends onto the truck. You will have a hump in the weatherstrip that did not go down. Using a small block of wood and hammer, lightly tap the hump down into place. This will tighten the weatherstrip into places like curves of the door way.
Suggestion is do this a hot day.
Removing the interior panels was the hard part. Otherwise, the installation of the weatherstrip was easy.
