9" Drum and Wilwood Disc Brake Conversion

Didn't work for what application? I understand Wilwood only works for 1964-72 cars, and there are different kits for 9" & 10" drum brakes, and none if the car has factory K-K disk brakes. I wouldn't trust the comments of someone who bought Wilwood thru Summit anyway since they give no value-added and might even mark-up the price.
