Interesting question. Never thought of it and how they would replace it. Bet they remove the back seat and slid it in. Worse case they take a cutting torch and remove the roof. But remember it got put in on the production line.

 

Very carefully

Instructions say through the right rear door, but the pictures show the left rear door & the instructions tell you to recline the left front seat all the way, which leads me to believe that it will be through the left rear door.

Hmmm....and where might you be getting this plethora of knowledge ...as in do you happen to have a manual that shows pictures or know where I can get them to bring to the dealership (Sad they barely know how to work on a vehicle)

 

^^^ the picture that shows how it goes in the car.

Did you notice the contradiction there? :wink2:

 

well I am an advisor at a GMC, Buick and Pontiac(till pontiac leaves) and I like helping people.

I do think the picture is backwards, but it says the right seat has to come out and the left seat has to be fully reclined.

Well that makes these forums really helpful, thanks!

 

ahh.. That makes sense, I was only scanning the instructions & didn't notice the removal of the RF seat... It still seems odd that they show a picture of the LR door

 

Yea I just saw removal of front right seat, fantastic, another piece that needs to be removed from the car, basically gutting the interior, I wonder if it is hard to remove the driver seat as well? Maybe give a little bit more room to get this thing into the roof? Never removed one of these seats before, I just hope nothing starts rattling and clanking after this is all said and done. Once again thanks for all your help.

 

its fairly easy to remove any seat from a car. IMHO as long as you dont remove the seat adjuster you will be fine.

While the seat is out, have them do the adjuster mod so the passenger seat goes back as far as the drivers

 

is this better?

 

Well I finally got the car back, looks great, all four corners are nice and snug, 3rd brakelight works, could never tell it was replaced. Patrick Pontiac FTW!
