anyone have impossible to remove grease cups inside front hubs?

Hello,
     I was planning on renewing the lower A-arm bushings today, but I didn't 
get as far as getting the hubs off.  The grease retaining cups immediately 
inside the front hubs of my 1968 MGB are stuck.  I have tried amazing amounts 
of leverage against nuts that I threaded onto the bolt that protrudes from the 
cup to no avail.
     Anyone have this problem?  Short of attaching a stinger missile to the 
bolt and letting to loose, I can't see how to remove them.  Maybe a couple of 
draft horses, one pulling on each hub at the same time?  :)

Benjy.
