Current one is worn out.


I'm sure you know you can put new shoes and spring in them. Also make sure you have the shoes in right, otherwise there will be slop and some folks think that means wore out?

In a race car or a very ridged chassis I wouldn't expect much flex, but these old cars in close to stock form flex like crazy and then the coupler has to move, imo. Maybe that's why they are saying that?
