I need new brakeshoes for my '78 because a small part on the corner is broken off, just at the rivet. The dimensions are: 180 mm diameter 25 mm width. Searching the web, I only came across brakeshoes 19 mm wide. Apperently the same as for the 997 (partnumber 997-352-993-01-M3).
I think I need the original width to fit properly.

 

Anyone ever fittedthe 19 mm wide shoes instead of the original 25 mm?
