i believe some kit cars have true IRS, maybe use one of these as a donor...
seriously though, what do you mean by proper IRS? you almost certainly wont find a donor that you can simply bolt it off and bolt it onto the kit.
most people who use IRS have made top and bottom bones, and a hub carrier, and use sierra parts to finish it off.

Couple builders have used the entire rear sub-assembly from the MX-5.

Some Tiger cars and Robin Hood cars use the complete rear subframe/diff/driveshatf/trailing arm assembly from the Sierra. Even then I believe you
have to modify the suspension pick-up points and method to use coilover shockabsorbers.
You could have a look at the book "How to build a Tiger Avon" to get an idea of how to fabricate an IRS set-up for use with Sierra
components.

look at it, see the shortfalls and design something better - it would not be difficult!
If you can keep you head, whilst all others around you are losing theirs, you are not fully aware of the situation

I know the 3 series BMW IRS has been adapted for use on triumph stags,not sure if its too awkward for kit building.
The sierra rear end is a bit of a mess if used in its entirety,i'm sure this is why upper and lower wishbones are used along with bracketing on
the chassis for the diff,keeps the weight down too.

I used the MX-5 as a donor, as did Bob C. Have a look at his archives for a good example.
My work can be seen here. Exactly the same as Bob Cs but with inboard dampers. The bits
are perfect for a locost and are very light.
