looking for locking hub

[Emery19]

well long story short, after rebuilding the front end on the plow truck, the passenger side locking hub assembly has mysteriously disappeared somewhere along some road in town. now i saw mysteriously, but im pretty sure its because the snap ring wasnt seated right. truck needs to be up and running for moose hunting this weekend.. i couldnt find the hub on rock auto which is normally where i buy my parts from, but i found some online for 289.95. i wasn't aware it was that expensive for that part. any place i can either find it cheaper, or do any of yall have one? any help is appreciated, but might just have to shell out the cash.

btw, its for an 01 350 srw

edit for a second time. manual 4wd, not auto

You can put a regular D60 lock out on it. Those should be easier to find.
