I have a complete 8.8 posi axle from a mustang sitting in my garage - will the center fit into the IRS of my mark?

also how many spline is the mark rear? 31 or 28?

to clarify, it's from a fox mustang.

yup, its a 28 spline cobras are 31 spline

so does that mean that my fox center will fit?

ANY 8.8 posi unit will work fine as long as its for 28 spline.

that is great news, I have been sitting on a rebuil 8.8 posi for like, a year. Finally gonna put it to good use. I am assuming then that Fox mustangs were 28 spline.

Yes.

waitt... lemme jus make completely sure im reading this right before i go to town.... If i get one of my friends fox body posi rears with 3:73's or 4:10's..... and its 28 spline, the rear will fit in my mark viii????? and will work wit my independent rear suspension

Yes 100%.
