Rear spindle/hub assembly/bearing 94 Infiniti J30

[Colts_rule]

I had a bearing go out on our 1994 Infiniti J30t. I ordered a bearing and took the whole spindle/hub assembly to Midas for them to remove the bad bearing and press the new one in. The guy at Midas said my hub is bad but still pressed the new bearing in. There is still a lot of play in the whole thing. So I went to try and order a new hub and a new bearing because my new one will get screwed up trying to remove it from the bad hub. They couldn't find the part. If I go to a junk yard what other Infiniti models would the spindles be interchangeable?
This is a great web sight with a lot of information.
Thanks for your help,

I believe the Nissan 300zx part from the same years are interchangeable.
