i new 2 new axle keys that go between the brake drum and the spindle. thanks Adam

On what car or truck? And do you mean the 1/4" square one between the rear axle and the wheel hub? Mine is 1/4"
I go down to the hardware store or parts store and buy a piece of 1/4" square key stock and cut it to length with a hack saw, actually I prefer to use a Dremel tool with a cut-off wheel in my old age.
Hope this helps and saves you some frogskins.

thank you, Adam
