8.8 rear?

[tarmon8r]

I just purchased another 83 Mustang, except this was is a 5.0. Mine is a GLX V-6 converted. This one looks like it has an 8.8 rear under it. I tried to eyeball measure it and its about right 8.8 but just eyeball. The think that caught my eye was what appears to be a mount on the axle for a quad shock set up. Of course there is no quad shock. I didnt think the mustangs came with 8.8 in 83. Just wondering if it was factory or if someone put one in previously. I bought the car for the body, fresh paint, t-tops, and new world class t-5. Paid $1000. Didnt even look at the rear. The car didnt run. This guy new nothing about motors. He had the fire order going clockwise. lol. Got the car home. Went over it. Realized the error. fixed a gas leak and it started right up. But i digress. Anyone know off the top of there head in 83 if 5.0, has a 5.0 badge, came with 8.8 rears. If it is.... Bonus.. And are there any other obvious differences or will I just have to crawl iunder the car and find a tag or measure for sure.? Thanks in advance..I put the chrome cobra r 17's on.
Peace.
