A few days ago I was painting a few of the underbody parts on my car and when I was back behind the differential I noticed it says "8.8" on it....did the 95 XR7's come with these?? Was it optional? From what I know the guy that had it before me didn't do anything to it except put the stereo system in it.....he didn't even have a K&N filter on the thing when I bought it...but he does work for Ford dealerships as a mechanic.....just wondering if this is normal to have the 8.8" rear end
