Only the Cobra IRS, for certain values of "just bolt in".

And why? On a 5.0HO, until you're pushing power levels that'll split blocks routinely, the 28 spline should be quite adequate. About all the Cobra gets you is 31 spline. Which changing the spline count would also call for new half shafts ...

And even then the outer splines are still 28

I've also wondered if I would be able to swap the solid axle from my mustang into my tbird but I've been told the axle tubes aren't long enough and mounting the rear end is different?

Just a bit, 97Tturd.

I have a really silly question.

If what you want is a Mustang, why not buy a Mustang?

Swap?

Why?

As was suggested, best thing to do is to crawl under there and look.

I mean, you have both - why not just look?

You ARE aware that they're not plug and play (Mustang to MN12/FN10) like the MN12 and FN10 are, right?

Well, with a cobra subframe swap, you can get IRS on the Mach 1 without worrying about making brackets. Do like I did and sell the New Edge, keep IRS in the bird and never look back. That GT I had was clean but it sucked. I did get beat by it on my bday though. It ran a best of 14.9 and I ran a 15.3 even though I beat it to the end. I was getting hella wheel spin. I cant wait to destroy this thing later with gears. Beating new edge stangs used to make me feel so good

There was a guy here in TN tht did a solid axle swap on a tbird. Never actually met the guy but he's on the tn mustang forums. Supposedly did it to loose some weight, I don't think he was happy with it tho. Sold it a while back IIRC

Why? I like them. Not as much the 99-04 but I like the 97 and 98. And they weigh nothing compared to our beasts.

In what way is it a POS? In your application, that is?

Its old, outdated, and for me, a straight axle would be better suited.
