Early 67 Cougar and Mustangs use the A/C or large vacuum tank inside the engine compartment under the RH hinge for vacuum for both tilt and A/C. The Trico valve has only one nipple on each side and goes in the large line between tank and engine manifold. With A/C there is a vacuum tee under the dash behind the instrument cluster that splits off the vacuum to the tilt mechanism. These cars will not have the holes punched out under the battery tray. I had a Sept. 67 Cougar and a Oct. 67 Mustang that had this setup.
