Using A2 rear Disks upside down on A1 Drum upgrade.

[ranahan@charter.net (John Erickson)]

My parking brake cable does not hit (I have the A3 rear 
calipers), but I removed the last cable bracket when I 
hooked up my cables.  These are the little brackets that 
attach on the two small nibs on the frame.  I had to pull 
a little slack out of the cables, but haven't had any 
trouble.  Maybe my cables are just old (certainly)and 
stretched :).
