Want to buy a IRS kit for the 33 hot rod
there really isn't a kit for IRS. Unless your frame was set up for it. If it had the IRS option then you can get the finish parts from lots of sources. Ford, FFR junk yards etc.

Your request is imprecise. Do you want the parts that FFR supplies (ask FFR) or the differential, etc. that are from a 2015 Mustang (try Mike Forte or rebuild junkyard salvage parts)?
Also, be aware that FFR modifies the Hot Rod chassis to accommodate the IRS. Adapting an IRS to a 3/4 link chassis would require some significant fabrication. Some prior (highly skilled) builders have adapted a Tesla and a BMW M3 IRS into the standard chassis so it is possible, but not frequently done.

Oops, I didn't see Mike's comments before posting. Sorry for the redundancy.

The IRS chassis is different from behind the cockpit to the back end. There are some decent drawings and photos in the section of the Hot Rod Build Manual about the IRS installation. If you don't have a build manual, you can download a copy from the FFR website for a nominal fee.

I have some IRS parts for Cobra. Some will work, not sure about control arms or toe links. A friend of mine did retrofit IRS on his 3 link Cobra.
