Out of curiosity, was this an original 289 car? Someone please chime in if ya know...aren’t there two different motor mount brackets? Small block and big block. Both look similar but there is a height difference for the mounts? I don’t know for sure since I have the early ‘65 mounts. I remember running across this information while looking at converting to the 66-70 motor mounts.

My 67 had 67 mounts and 68 isolators (Anchor #2257) that took quite a bit of prying to get installed. Back then I did not know any better so I pried them into place. This spring I researched the problem and found out about the oddball mounts/isolators ford used in 67. I contacted Glazier Nolan and had them build me the correct (#2286) isolator. Dan basically cuts up a new set of 2257's, installs them in a jig and welds them back together to #2286 angles. The new modified isolators fit correctly and lowered my engine by about 1/2-3/4" measured at fan (it is now centered in the shroud). If I were to do it again I would purchase the 68 frame mounts and use the over-the-counter Anchor #2257 isolators to get the same easy fit and proper engine height. 

I found this on the internet when researching the 1967 engine mount debacle.

After 11/1/65, The design changed completely. The frame brackets were stamped steel, and the insulator and upper bracket were all one piece (marked C6OE or aftermarket #2257). There was no left or right insulator, the same part was used on both sides. Also after 11/1/65, the unique 289HP mounts were discontinued, all 289 engines used the same mounts.

The most confusing aspect was when Ford altered the angle of the insulator in 1967, which required a new insulator (marked C7ZE or aftermarket #2286) and bracket assembly. This altered the mounting angle of the insulator to control vibration. Oddly, the 67 frame bracket was compatible with either the 289 engine, or the 390. The bracket varied in the location of the outer bolt hole. 

In 1968, Ford changed the design again, altering the bracket on coupes and fastbacks to use the 66 style insulator, but retaining the 1967 design in convertibles. This continued through 1970. Oddly, the 1970 BOSS 302 used the 1967 configuration.

Great care must be taken when replacing motor mounts. Although many suppliers offer a correctly-numbered mount for the 1967 design, it has in fact been replaced with the 1966/68 design, and will not fit properly. Glazier Nolan can provide mounts which fit the 1967 design.
