If they were off an LC LJ Torana they should fit but the later Toranas had wider bodies and wheels were sometimes more dished on these models.
It is a well known fact that HK rims do not fit FE FC - HT HG rims will fit OK. This is an example of wheel offset being changed to suit the models as they go along. Just because a wheel has the stud pattern you need doesn't mean that it will have the offset you desire. These things need to be checked VERY carefully before large sums of money are outlaid.
A short story made long............
Working in the hotrod business at Hoppers Stoppers we would see customers bring in projects to be fixed because they went about the car design all wrong. They shortened a diff then bought brakes and lastly chose a set of wheels they liked only to find that the whole package didn't fit. If you have your heart set on a wheel for your project then the method should go as follows;
If you have a fixed front end (such as HR in a FC subframe) you need to buy a wheel which will suit your needs (ie are the guards stock or flared, is the car lowered or not). The offset of the rim has a big bearing on the look you want to achieve. (ie Commodore offset is good but doesn't suit an old skool look). But there is no point buying a deep dish rim if you are using bigger brakes on a lowered car with stock guards - it just doesn't fit
So.....Decide on wheels first
Ensure the brake package you want (or your engineer tells you you must have) will fit inside the wheel and the wheel will then fit the car.
Purchase wheels ONLY after all the above has been satisfied.
Set wheels up in car and measure flange to flange distance - this is the final length the diff must be to accommodate your wheels.
Have diff shortened to suit.
So how does old skool work? Simple, the cars mostly had stock brakes and were not massively lowered so wider deep dish wheels would fit OK. Check out pics of Alan Hale's black FC with the 350 Chev from the 70's and you will see what I mean.
