Shackle fits my 1969 Mercury Cougar perfectly; Bushings will not fit the 1969 Cougar. Staples come with 1-1/3 inch diameter bushings. My Cougar requires 1 socket. I'm sure there are some applications that require 1-1/3 jacks. My recommendation is to measure the spring bushings and if it is an inch those bushings will not fit.
