A friend of mine has a wrecked late 80's mustang with the four banger. Just wondering if anybody would know what rearend it had in it, I know it's not a 9 inch or anything like that I just wondered what else it could be. Thanks

 

Ford started using the 8.8" rear in the Mustang starting in 1986 and was the V8's exclusive rear end.
You have a 7.5".

 

Thanks for the info. So basically that's why we wanted to give it to me free.
