Brake drum screws

[John Mitchell <jmitch@snet.net>]

    I was just wondering about the 2 small screws that hold the brake 
drum on.  I have some alfin drums without the screw holes and wanted to 
know how important it is  to add the holes.  Seems like the drums go on 
fairly tight anyway and of course the lugs  hold them on too.  I just 
remember what a pain they were to get out the first time I took the 
drums off.   Thanks for any advice.  John Mitchell  76 TR6
