How To Install Adjustable Engine Mounts

Once the locknut that ties the engine mount and frame bracket is removed, take out the mount as shown. This is the actual engine mount, a small rubber block that didn't do much of a job for vibration isolation.

Next, remove the cast-iron frame bracket. Although this is a California car, the bolts were rusted and decidedly stubborn.

Although we call them two-piece mounts, they're actually one-piece with a cast-iron frame bracket. If you don't need the adjustable Ron Morris Performance mounts, you can improve NVH on a '65 Mustang by using '66 or '68-'70 frame brackets and improved engine mounts. Be advised that '67 frame brackets and engine mounts are stand-alone and one-year only, which is why we want '66 or '68-'70 brackets/mounts.

The Ron Morris mount installation begins with engine brackets, which enable you to slide the engine fore or aft depending on transmission type. Rarely would you ever have to use this feature in a classic Mustang, but it's nice to know it's there. The angular end goes to the rear on both sides and squared end to front. Install and tighten.

The frame brackets bolt on like this on both sides of the shock tower cradles. Common cadmium-plated Grade 8 bolts tie these pieces together with locknuts and flat washers. We suggest using Grade 8 flat washers on both ends.

This is how your Ron Morris engine mount configuration should look before the mount goes in. Frame bracket stampings are universal. However, if you want it to look impressive, position the sharp edges in and the rounded edges out. The same is true for flat washers-smooth edges out, sharp edges in.

Here's the left side mount loosely installed with everything in place. If your Mustang's framerail dimensions are correct, no adjustment is required.

The heart of the matter is this clever urethane mount that absorbs vibration and noise. Ramon's Automotive installs the mount loosely because it will have to be centered on the frame brackets once tied to the engine. Frame brackets have been removed for this step.

With all pieces in place, run the bolts down until tight. Although a torque wrench is recommended, it is not mandatory. Get these bolts good and tight, but do not overtighten.

Sliders are tightened last. Check it out-good-looking engine mounts that will yield quiet operation and ease of service.
