o Change 15.10.J to read:
“15.10.J Engine mounts may be replaced, but must attach in the factory location(s) without additional modification or changes. Engine position may not be changed.
Hydraulic shock type rear engine locators, or bobble struts may be replaced by manufacturer’s performance part, or aftermarket replacement part. This part must retain factory dimensions and attachment points, including factory design. (Example: If factory locator/bobble strut is gas or hydraulic piston type, replacement part must be gas or hydraulic piston type.)”
