HI EK amigo,
from what I can make of your pix - the one one the left is HR - new they are a thickness of .375".
Both HD and HR had twin piston calipers either PBR or Girlock. The bore diameter of both pistons is 2 1/4".
The second pic, I believe - is possibly from a later Torana .... to me, this appears to have been fitted to a vehicle with 5 stud 13" wheels - but I am a little concerned with what appears to be a wider stud pattern...... and cannot be confident of my observations in this pic....
the pic also suggests that a "floating" single caliper is fitted..... which is definitely not HD/HR...
I believe both discs are of 10" diameter......
frats,
Rosco

The rotor and caliper on the right is LX or UC.
LH had a cast iron caliper.
If you use these on a HR front end you have to swap them side to side.I think you need to grind just a bit off the x member for clearance as well(sorry,its been a while..)
Ive used them and had no troubles.
