The Wittek Company manufactured the tower clamps used on the Cougar from 1967 to 1973, the Mustang from 1964 1/2 to 1973, as well as many other Ford and Mercury cars during that period. In October or 1993, the company filed for bankruptcy. This has made the tower clamp unavailable to the classic car restorer. Our supplier was able to bid at the auction for enough of the original tooling and parts to make these clamps available again. Other companies have also reproduced these clamps, but neglected several critical factors in their design. These Wittek clamps are hardened to the correct Rockwell hardness. Other suppliers did not take this into consideration and now customers are experiencing breakage of the clamps upon tightening. These clamps have the correct hot-dip galvanized plating so they have the correct appearance. Our supplier has every unique bridge for the clamps, not one size fits all that distorts the clamp and does not provide sufficient sealing.
