Thread: Polyurethane motor mounts

I installed a energy suspension lower engine mount

Some drilling requiredas well as shims (oversized nut and some washers) but I installed a energy suspension mustang transmission mount as the lower engine mount (4.1104), and may try the same for the transmission mount with a gm trans mount (3.1108) smaller than the mustang mount.

For the engine mount I used shims to bring up the base to the same elevation as the origonal bolt holes, just bolted down to the bottom pan of the engine mount (2 holes drtilled) I drilled out 2 holes matching the upper's spacing as well to allow me to ream out one hole, and offset the other allowing the poly mount to be easily replaced if required for future use/ replaced by the same style rubber mount if I didn't like the feel.
