IRS for f-bods
I was thinking, would the IRS for the GTO fit the F-body cars with min.
modifications to the F-body?
just something for you guys to think about trying.

Is your goal for better handling or smoother ride? It certainly couldn't be for decreased weight or better drag racing launches.

some other people asking about the IRS from the corvette, thought the IRS from the GTO would be easier to install than the unit from the vette.
just a thought, trying to get some opinions about it.

I just think you dont know how to weld and have no imagination. Cutting up cars and peicing them together is what this hobby is all about. Thats how it started, with Tommy Ivo sticking a 401 NailHead Buick V-8 on a 32' Ford Model A Frame with a 27' Model T Body.
Any way if I were trying to stick a IRS under the rear I would do what all the 50- something "Diaper Rod Rubbers" do and buy a IRS system aftermarket.

It was done before, so with a little imagination it could be done.

My understanding in the beginning when they brought the GTO out was the diff was suspect. Prolly one out of a C5 would be better. There are also companies out there that put a full C5 suspension under a old '55-'57 shoebox so anything can be done if you want to.

If you are going to go to the trouble of an irs conversion for an fbody, I would use a C5 rear over a C4(or anything else). It has the tranny in the back, which improves weight distribution. You might as well grab the LS1 if your fbody does not already have one. Then again, if you do both, it would probably be cheaper to just get a C5. You can get a good one for mid to low 20's these days.

Believe it or not, the stock axle is the lightest OEM suspension setup out there. Yeah, there is more unsprung weight than an independent, but the total mass compared to an IRS is usually less... and cheaper.
That said, I have driven both an F-body and a GTO at the limit, and the GTO will always feel more planted, the F-body takes more attention if trailbraking into a bumpy turn, the axle likes to tramp around, and you need a little more steering input to keep the car under control, but it has a higher lateral g capability. I ran my GTO with some retired A-sedan F-bodies (3rd gen, but same suspension as 4th gen) and it they could flat out corner me.
On a tight back road, with less run off room, I always seem to run the f-body a little easier than the GTO. YOu just can push the GTO closer to it's limit and not worry about the tail dancing around..
I am not a big fan of F-bodies <duck> on the street, but they are damn fun track cars..
