The stock banjo rear in your car is about 61 to 62 inches wide, as I recall from looking at mine. How wide is the 8 .8 you are looking at? The one problem with 8.8's in general is that there is a lot of bracketry to cut off to get them clean enough to use under a 46. An 8 inch or 9 inch is generally so much easier to install and clean up.

The right way to find a perfect rear is to first buy the wheels and tires you will be running on the back, prop them up under the fenders to where they look right, then measure the distance from wheel mounting surface to wheel mounting surface. That is the width rear you need.
