I've certainly seen it done.  The shock towers are going to have to go, so the first order of business is going to be to eliminate those and install a Mustang II style front suspension.

The IRS rear is going to be tricky because there are no mounting points for it.  Crossmembers are going to have to be fabricated, braced, etc.  The Cobra IRS isn't really known for being super durable.  A lot of guys swapped them for solid axles, which is why you always seem to be able to find them despite the car being a fairly limited offering.  The differential is basically an 8.8, but uses an aluminum housing.  I believe that some T-Birds had the same center section, but it was iron and some guys swear those are better strength wise.  IMO, unless you want the cool factor, I'd skip the IRS.  Its not as great as people think for handling, and the geometry can be a nightmare to set up right because IRS setups have an inherent lack of anti-dive and anti-squat.  The handling, especially in a powerful car can be dangerous to the uninitiated, because you need power to plant the rear wheels.  If you lift mid turn, or get scared thinking you're going to fast into the turn the rear tires unload and lose traction causing the car to get light in the rear and start to do this death dance as the whole rear suspensions fights itself.  I've seen guys wreck when this happens.  You have to get used to powering through turns, which is equally dangerous in high powered cars because if you go too far now you're in a power induced slide, where the tendency is to let off and regain control, but the instant you do that see my previous statement.  IMO a solid axle coilover rear setup using one of the various link systems out there is an infinitely better choice for a Mustang than IRS. 

We are in the process in the 66.

Day has figured out how to install the Jag IRS (It's as strong as the Ford, so I'm told) and it may be a bit cleaner of an install than the Cobra unit. 
Sounds like a great project...can't wait to see it at the 2017 BASH.  Or, if you are really good, the 2016 BASH.

Good luck, have fun.

if i can get a fast boat across the atlantic i will bring the car over,i'm in scotland usa.The reason i want to use the cobra  drivetrain is i got it cheap way too cheap prefer to keep my car all ford.I was recommended a company called dvs restorations  who sells the rear mount kit for cobra irs $3k ouch,Jag stuff is very cheap over here to 200 bucks gets you a rear axle

Jaguar was owned by Ford at one time, so its still okay in my book.  Again though, I'd just sell the IRS stuff and put what you get for it towards the rest of the project.  A 9" is a Ford rear...

We are using a wiring kit from The Detail Zone.  Here's the link. http://www.thedetailzone.com/ford%204.6%20&%205.4%20efi.htm
 

Not as cool as Timc but I've done a 98 cobra swap.
