Motor Mount questions

What is the difference in the motor mounts between '65 and '66? Does one set the engine lower then the other?

No, they were the same height. In the fall of 1966, Ford switched to a simpler, cheaper motor mount. Contrary to rumors, the engine sat at the same relative height in all Mustangs, regardless of body style, etc.

I'm glad this question came up, I got my mounts out of a '65, but my car is a '66.

The other thing I've seen on this forum is concerning header fittment, and usually the suggestion has been to switch to the '66 mount, why?????

Beats me why the C6OA would be preferred. Maybe because there was no left and right insulator to mix up, both were the same.

I think where this myth got it's start is from back in the '70s when guys were modifying the stock '65 mount "L" bracket to lower the engine and set it back. Out here, running '65 mounts became synonomous with lowering and moving the engine back. Hence the rumor that '65 mounts lower the engine. Kind of the "cart before the horse" type thing.

The 65 mounts are thinner only when made in a dirt-floor factory in a 3rd world country.

There is a difference in height between the C6OA and the C7ZA, but this is due to a difference in the mounting angle of the frame bracket, and the engine ended up at the same height. If you mix them, all sorts of odd thing happen. The C7ZA (industry number 2286) is not available anywhere.
