Ford 8.8 Junkyard Score

That appears to be a 4 link coil sprung pass car axle. What did you get it out of? Mustang, Crown Vic? What's the outer tube diameter on it?

The explorer 8.8 uses a 3&1/8" diameter axle tube. With that you will need to use the ford U bolts and oval out the 8&3/4 shock plate holes to fit.
