Front axle with factory lockers come reinforced stock?

[SuperDuperCruizer]

I've seen some FJ60 axles without the reinforcement... is this something toyota did on later axles or just for factory locking axles?

here's a link to some pictures of what I'm talking about:

Thanks for any information, SDC

The gusset comes in 1988-1990 cruisers. True, never seen factory diff locks without the gussets unless retrofitted.
