33 Rear brakes

[Kpar]

Well after a $700.00 bungle with my last (and final) purchase from Mac's I've listened to Barners and decided to repair what I've got. I will use some of the bits they sent me though.
What I'm asking "is there some schematics or measurements on the rear brake track" Mate Lawrie has offered to build these up and machine back to original.
If there are measurements available it would be a lot easer.
