You could use HQ stub axles and brakes, but that will change your stud pattern - original HR disc rotors are still available if you want to go that way. HK-T-G will keep your stud pattern the same but you must run 14" rims. You could spend up big and go for a Hoppers Stoppers set up .
Theres lots of options.

you can get adapters but not really worth it when all you need is the stub axels and everything attached to them, once removed at the balljoints
you can get these from a variety of cars of coarse HD/HR 13",H/KTG 14",H/QJZX 14"different stud pattern, LC/LJ torana 13",LH/LX/UC torana 13"
with the later toranas and i think the H/ZX you may find wheel alignment difficult
i have used all of the above except adapters

Hi
I am in the process of changing my front end from standard to disc.
Using a HR front cross member with HT stubs due to no stubs with the front end I got (for $60 for the cross member you can't complain) and torana discs(Cheaper to get parts for) to keep the early stud pattern.
You can purchase boosters new from Hoppers Stoppers or rebuilt from Hydroboost, I've been told you have to use the VH40 only.
Check out this guys link he does a conversion on his EH

sorry for wrong information
but my info was incorrect, torana brakes will not fit HT stub but will fit onto standard HR stubs.
I've ended up using HT disc and torana calipers, allows you to go to 14 inch rims and keep the early stud pattern, you need the hat section for the discs as they are two piece.
hope this helps

Thanks Marty, it fits will other images I have found today.
The PBR unit must be a Torana caliper, as it doesn't have the same shape as other HK, HT, HG calipers I have now seen. Unless the PBR units were an alternative to tghe Girlock units.

Thanks again

Yeah you are right Finny, it is the Torana ones as we had some issues with the HT calipers but I can't remember what they were.
