Which retainers were used for the strap for this example?
The retainer is Ford p/n C7OZ-3E523-A, called "Cilp, Power Steering Hose" but shown as "6E523" on the 68 Chassis Assembly Manual, pg 70. (The portion of the same drawing in the 67 Mustang Chassis Assembly Manual, pg 49, is "washed out".) Per the 75 MPC (sec 35 pg 14), it is used on 67 Fairlane, Mustang and Falcons with a 289; and 68 thru 71 Fairlane and Falcons with either a 289 or 302, no Mustang reference. The strap in the 68 Manual is shown as "3C696" but does not show up in the MPC. Neither item appears in the Illustration Section.
