The forum has good info on front brakes, but not rears. I'm planning a conversion to HQ pattern on the front, pretty sure I have Torana bolt pattern on the rears.

I've measured ~245mm, or 9.6 inches across the outside of the drum as shown below.

It's stock LH right? I want to keep the original master cylinder, and go to either HQ drum or a rear disc setup. Has anyone recently done this and have any tips?

Thanks, these guys are attached to a 9"; for least fuss to getting to HQ pattern, I think I'll follow this thread:

Converting to disc appears to require welding and new handbrake installs, argh

What needs welding ?

And you need to play with handbrake cables to put Q drums on anyway
