As Bill noted space is a little tight but I replaced everything on my '70 without releasing the axles.  The first one takes a bit of time but the second one goes quicker.  Work one side at a time so you have a reference to look at if something doesn't look quite right going back together.

Thanks,  I'm sure I can do the repairs and O yes I surely was going to only do 1 side at a time so I could use the other side as a reference point. 

The easiest way to get parts from Bair's is to give Brian a phone call.  He can also answer your questions.  ;-)
