gq steering damage after day out

i guess i will check the workshop manual ... cheers

my workshop manual only shows removal and instal of the steering box, does anyone know which manual has a rebuild section for the box, or at least some diagrams of the parts of the steering box, just trying to work out which parts might need replacement besides the gasket, so i
can decide whether to fix or replace

Looks real bad but you got home

sooo... does anyone have a gq or gu steering box (not leaf sprung version) that they would part with ? :)
