Need to confirm this information:

Is the 99-04 Mustang 8.8 rear .75" longer on either side than the previous 8.8's? Any idea if the width of the 99-04 8.8 is the same as the IRS width? Can't seem to find any reputable sources online to confirm this information.

Thinking about calling it quits on the IRS swap for now. With the front suspension and wheel combo I'm planning on using, the IRS width is what I am looking to obtain...so I think the 99-04 GT 8.8 will match that width.

Thanks.
