Robert,

Are you running a 'stock' bugeye rear end with brake backing plates off of a 
much later model?? If you are, the clearances between the brake drum and 
backing 
plate are MUCH closer with this combination. When I did this conversion to my 
bugeye, the rear face of the brake drum itself was binding directly against the 
new backing plates, so I had a machine shop remove about 1/16" off the back of 
each drum which resolved the problem. From what another lister here told me, if 
the later 1/4 leaf spring rear end is used, that came with the later brakes, 
this would not be an issue, but on a 'stock' bugeye rear end, it's definitely a 
problem. 

BTW - the brake drums on all years are the same, so only the positioning of the 
backing plate to the hub was changed to accommodate for the newer style backing 
plates.

Regards,
Bryan Vandiver (59-bugeye)
