Here is a possible solution for the "wait six weeks" dilemma: Your pinion seal is a pressed steel shell that holds a felt wiper ring and normal commercially available seal. Being cheap and in a hurry on my own cars, I rebuild the seals and put them back:

Carefully pull the old seal with a good seal puller, or by grabbing the nose of the the seal with a pipe wrench and twisting it out. You can now punch out the center section of the pinion seal and replace it with a new one. Use a good sealer and around the new center,and also upon insertion of the assembly into the rear axle.

It will be just about impossible to obtain the drag that Packard specified without taking everything apart but my best suggestion is to keep tightening the nut a little at a time til the bearings take up--that is you can no longer obtain any endplay on the pinionshaft using a dial indicator. I'd probably give it another 1/6 of a turn after that and stake the nut.

The seal you want measures 1.625x 2.437x.50. Over here, that would be a Victor 46281 or Chicago Rawhide 16117.
