Stock guard to hub centre dimension (1 Viewer)

[MrThing]

Hi all. Is anyone able to point me to somewhere I can find stock dimensions for the guard to hub centre on an early 90s PZJ77 or similar?

Things are feeling (and looking) a little saggy so I'm going to have a look at having my leafs reset.
