whats the width of the tgp trunk? need for new spoiler

[1trucavalier]

how wide is our trunk?  I found a new wing (stocker wing was spray painted and attached wrong so it was leaking throught the weather stripping  :evil:  grrrrrrrrr).   The wing I found is 56" wide the pedestals are about 1 1/2' feet wide so I know thats not a problem.  I just don't want a wing thats to wide or to short.  I guess the overall width of the car is what I need.:?:   If possible please replay today.  Its a one time sale item that was originally $350 and they want $99 its the last one.
