[6pack] hub remove and replace

[dave]

?hi, all.

it seems that the right rear hub is bad on my 72 tr6.  you can rock it back 
and forth quite a bit, and theres a definitive vibration on the right side 
above 35 mph.

ideally I'd replace the whole rear end with nissan and goodparts, but right 
now I'm busy paying college tuition.

I have a friend who has two tr6 parts cars.  assuming there's a good hub 
there, here are my questions:

1.  are left and right interchangeable?
2. for a shadetree mechanic with the usual craftsman tool box, can I remove 
and replace them?
3. the rear brakes are slightly modified - I've got the Morgan brake 
calipers - how does that affect things?

thanks in advance!
