Ed I could not find it on the SAC site.
I talked with John Murphy yesterday, he own a very original 68 GT-CS that has both AC and tilt. He said that his car does not have the 3A762 retainers. It got me thinking may be if a car had tilt and AC the retainers may have not been used because the AC hose straps also held the tilt vacuum lines in place to the shock tower brace.
