how much would this cost? (estimate)

You are looking at a major project. The Crown Victoria is a body on frame live axle rear wheel drive car. In order to go to independent rear suspension you would have to have a donor car the had IRS and the same track width as the Crown Vic. The differential on IRS is solidly mounted to the frame and uses swing axles and CV joints to articulate each rear wheel. You would have to fabricate mounts for the diff to the frame and attachment points for the rear suspension components. Things like ride height and spring rate would have to be calculated and adjustments made to the rear springs and shocks.
Big messy job with questionable results.

Find a donor Mustang with the IRS, then just remove all the attaching points of the original live axle off of the Crown Vic, weld in the needed brackets for the IRS that you can cut off of the donor Mustang, and get new axles that are the correct width for the bigger Crown Vic.
The car may need additional structural support to help keep the Vic from flexing too much under the different stresses caused by the IRS.
This cost varies, but finding the donor Mustang will probably be the hardest part.
It would be cheaper to buy a Mustang and just enjoy the IRS that way, or upgrade the bushings in the Crown Vic.
Do you plan on road racing or autocrossing the thing or something?

Why would you want to waste that much money on a 13 year old vehicle? You would need a "donor" rear axle and and rear suspension assembly, possibly a Mark VIII/Thunderbird/Cougar, from around that era. Even with that on hand, it still wouldn't be a direct "bolt in". You would need to modify the lengths of the axle shafts, and fabricate the mounting points on the body. After all is bolted in, you would need to do an alignment. It's A LOT of work, if you ask me.
