Things I haven't mentioned specifically: driveshaft, master cylinder, prop valve plug, external adj prop valve.  And I may remember something else.

ok, well I have an aluminum driveshaft waiting to be cut (will my stock  or the crown vic interceptor  bolt to the IRS?), already have 98 cobra brakes on all 4 corners with matching MC and porp valve so the system is setup up for the IRS brakes (are they different than the straight axle brakes?).  let me know what else you think of.  thanks

the companion  on the IRS diff will depend on what year IRS you get. i got a 99 IRS with an 03 companion . i robbed the companion  off my stock 8.8 for the IRS to reuse my stock d/s. either way you should already have the parts you need to make it work.

the calipers are the same, the rotors are 11.65" vented. you would be fine there too as far as the hydraulic part of your system being up to task.

cool, thanks

And I think it was mentioned already, but do you know the track width difference in the 03-04 IRS compared to a 96 straight axle (mustang)?

The 99-04 is about 1.5" wider overall.

Ok, so I'm confused.  Basically, what I'm trying to figure out is if my setup:

Stock 88 TC 8.8 with 96 mustang axles/brakes

is wider/more narrow/same width as the 99-04 IRS...?

ALL the 99-04 stuff is wider than the 87-88TC or 94-98 8.8...

So, another question, how much do the bottom mount points on the cradle have to be stretched forward to retain the stock 88 thunderbird wheel base.

LOL... hmmm...  Is the 'maybe' you're way of saying you're unsure?  I'm sure I can find the difference between mustang and 'bird lower arms and use that amount. 

so did you do the work yourself or take it to someone?

"maybe" because there seems to be some variation in the way the IRS fits, your best bet is to test fit.
