What year Cobra IRS fits the Mark. The guys over at GMvsFord don't believe me that they are a direct swap. Maybe I confused them because I keep saying IRS when I just mean the diff/pumpkin.

You're just talking about the differential housing, right? You don't swap the whole axle, do you?

Yeah, just the diff. I don't think the entire axle would work because the shafts are different lengths.

it can be built using a mustang GT rear as a doner though... cheeper too
