Kwazy: What Bill said is right on the money. The '05/'06 Tacos have the "glued" in windows. Better left to the window experts. The older Tacos (pre-'05) use the gasket and Rob has described the kit as "Great for the DIYer".
Bill: Great advice on the back seat. I was going to go by the installer and see if there was anything else that I could remove prior to install to save him time (and me $$).
BTW Bill mentioned the installation instructions in an earlier post. He has been kind enough to provide us with scanned copies of some of the pages of the installation instructions for the Powr-Slider in a Tundra. They can be downloaded
