I just checked, they all do include IRS 1989-1997. I do remember there are differences in the IRS for the turbo coupe 4cyl, supercoupe super charged, 3.8 V-6 and 5.0 liter V-8.
If your car is not setup for the IRS, it will be a pain in the butt to install but it can be done.
I can admit when my post is incorrect but don't mention the word HATE Woodz, the world is full of it already. Get used to another word if you can.
Thx, JQ
