My '66 does the same thing, as soon as I get the '93 running I'm having both rear bearings replaced. Just a guess, but I would imagine your noise gets worse if the cars driven for a while?
The bad part (at least for me, and I
think yours is set up the same way as mine) is that you'll have to have the bearings pressed on by a shop unless you happen to have a hydrolic press in your shop. From what I gather its not that expensive tho. I would just take the whole car in to the shop , but you can just pull the axles out and take them in. Also from what I understand, you should just go ahead and do them both at the same time, lest the problem manifest again in the near future with the other side.
Hope this helps,
J
