Will an 8.8 posi center from a mustang axle fit in my mark?

[67Continental]

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?

 

[67Continental]

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

 

[67Continental]

to clarify, it's from a fox mustang.

 

[Markviiiedrea]

yup, its a 28 spline cobras are 31 spline

 

[67Continental]

so does that mean that my fox center will fit?

 

[ONEBADMK8]

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.

 

[ONEBADMK8]

Yes.

[ONEBADMK8]
