Well,there were no factory K/30s.It could be a C/30 Napco conversion.Most likely a K/20 and some HO52s had the pre-load set on them.Only the brakes and bearings vary between HO52 and HO72...other than the pre-load.

Rear disc brakes were probably onstalled as a cheaper alternative to buying drums for these rear ends. Discs are all later model stuff with 14 bolt brackets.

The front has the disc brakes, not the rear. Sorry about that

It is a 3/4 ton. Front discs were standard starting in '71.
